Utterly shambolic communication.

Utterly shambolic communication.

Currently waiting 5 weeks for even an acknowledgement of my initial email in order to return the vehicle. They couldn't even pass the details over in a timely manner to the collections company.

So I've been stuck with a car I no longer want which I've had to tax and insure while these absolute sausage rolls of a company send me letters trying to tell me I owe them money for an agreement that's ended.

Avoid at all costs.

Don't get a GAP insurance with them!

I recently paid off my car I financed with them using a transfer fee. I got the title by mail. It was fine up until this. I wanted to cancel my GAP insurance that I had with them. They requested an e-mail with a notice. I sent them that and didn't hear anything from that for two weeks. I called them and they didn't see anything about the termination of that contract in their system. They somehow initiated the process in their system and told me to call back a week later if I don't hear back from them. I didn't hear one bit from them and called them back a week later. Apparently nothing happened and they told me they'll forward it to the team again. Meanwhile my account was charged and will probably be charged next week if they don't send me a confirmation that the contract is terminated. They are taking two months on this already without an end in sight.

Customer service who?

The customer service or lack thereof is woefully below par. The accounts team are uncontactable and each time I call I have the pleasure of dealing with yet another lack lustre representative, who, after answering a plethora of questions to confirm who we are, cant actually do anything of use.

It’s a simply copy invoice request and so far I’ve wasted 3 weeks of chasing for them.
I would only recommend this company as a practical joke!

Disorganised chaos

I had car finance with this company, my agreement was coming to an end in three months time and they wrote to me to ask what I was planning on doing. As the car was on PCP I had four options. I sent back the form as requested saying I was giving the car back. A month later they wrote to me again saying what am I doing with the car. I sent the form back again saying I was giving the car back. I rang them to check if they received the original form to which I was hold the second letter was a clerical error. A month later a third letter arrived asking what I was doing with the car I sent it back again and called again and they again said it was a clerical error and arrangements would be made to collect the car once the agreement ended.
A month later the day my agreement ended they tried to take £13000 out of my bank account. Luckily I noticed this and reversed it with my bank.

I called again to find out what they were doing. First person said I failed the security questions and hung up second psssed said I passed the security questions ;with the same answers) put me on hold and hung up. Tried a third time and no one could explain why. I told them well my agreement has ended I’ve cancelled my direct debit come and get the car whenever you’re ready. The car sat there another 6 weeks. I sent numerous emails complaining and reminding them the car was still here and received no response to any. Then out of the blue I got a letter asking why I had cancelled my direct debit. I called again got through security on the second time again (giving the sane answers both times) to again be told that it was a clerical error. I reminded them the car was here awaiting collection. They said someone will contact me. A week later I hit a letter threatening legal action unless I paid them the £13000 pounds. I called again (passed first time this time) again got told a clerical error and ignore. Two weeks later someone eventually called to arrange collecting the car.

I have sent close to twenty emails to their customer service to date not one response has been revived but when I call they say I can see you have emailed a few times.

I will never use these again totally unprofessional and dis organisation chaos.

Nightmare, drawn out, unprofessional VT process

I’ve been trying to complete a voluntary termination process with this company after repaying more than 50% of the total value of my vehicle.

I initiated contact on 8th June and was told the process would be straightforward, however I’ve found the process to be the complete opposite. After hearing nothing for 4 working days, I followed up with a call and tried to get a vehicle collection booked in. Mobilize then told me I’d need to phone the conversation directly. I’m not sure why; surely it’s Mobilize who hold the relationship with the third party company and should do this on their customers’ behalf if they’re unable to manage the full end to end process in-house.

I then went on holiday and received an email from Mobilize explaining that I needed to complete a questionnaire via telephone. I explained that I’m unable to call the number provided by Mobilize whilst out of the UK as the call won’t connect. I asked if Mobilize can help me by either calling me, or by emailing the questionnaire. Mobilize refused to do this and said I need to complete it by telephone. My question in response to this is why was I not asked to complete this at the time of me initiating the voluntary termination? Why was this requested almost a month down the line?

My only thinking is that this is a deliberately ploy by Mobilize to push back the termination date. I’ve already had to make one additional payment since requesting the VT. I’m now expecting Mobilize to drag their feet in seeing this through to completion in order to force another payment from me.

A very disappointing and unprofessional process of dealing with Mobilize would be summarised review and definitely a financial services company to avoid in future.

Nice people but very poor service

I have bought a battery and a car at DIAC. All the staff I have been in contact with has been very nice and polite. But most of my emails stayed without an answer, they withdrew money (each time 800 Euros) without explaining why, and now I have paid both items, and sent them the proof of it, they are still sending me letters about unpaid bills and extra charges. The extra work for having the bare minimum service is unbelievable.

Absolute shambles…

Absolute shambles of an insurance company. Obviously you expect them to try and get the best deal for themselves, but the process was so slow, the estimates ridiculously low and the jumped up to more realistic levels after a few months of battling. Then on other items they wouldn't pay out or give a break down of what was paid for what. I can't fault them enough!
