System Mechanic renewal subscription issues
I paid a renewal fee of around $25 (I think), but this company has also billed me a further $85 (or thereabouts). They are supposed to have a live chat facility but, for the life of me, I cannot find it anywhere on their website! I no longer have faith in this company and, when I am finally able to speak to someone from their billing dept to demand a full refund of both subscription fees, I will be uninstalling this product!! 🤬
UPDATE...
Managed to get a link from an advisor that let me view my subscriptions, but lo and behold, they don't do refunds, so I'm stuck with this program for another year, and will no doubt be auto-renewed, as per several other users' experience.
UPDATE (2)...
IOLO responded to my review on the 1st of December - 28 days later, I have yet to receive a response to the direct message I sent them. I can therefore only conclude that this is a disreputable company, with absolutely no interest in customer satisfaction. Once my (unwanted) system renewal expires, this company's software will be permanently removed from my computer.

Dear Steven,
Thank you for updating your review and sharing what happened. I’m really sorry for the unexpected charges and the difficulty finding a clear path to support.
Rest assured, your comments about auto-renewals have been taken seriously. I’m going to review your interaction and the billing associated with your account so we can better understand how this unfolded and make sure the experience is improved going forward.
If you’re open to it, please reach out to me at reputation@realdefen.se so I can personally see what resolutions may still be available for you.

Thank you for the kind words about System Mechanic, Fred. We appreciate your trust and are here if you need anything.
Customer service is anything but service
The software of System Mechanic is very good. Good product. HOWEVER...on a recent promotion you get a $19 a month extra fee for live tech support added onto the promotion. IOLO clearly stated you can remove this cost by calling them. It is like pulling teeth to get them to drop that fee. This is not the first issue I have had with customer service. I know nothing of their technical support. Just customer service is a high level sell operation. Buyer beware.

Automatic renewal
When I purchased Iolo VPN, I did not realise that it was going to be automatically renewed, and the renewal has come at a time when I really cannot afford that money, having been a victim of a scam. Iolo was unrelenting - they cancelled the automatic renewal but not the current one that I have been charged for. So I will be advising ALL of my existing clients (over 500 in total) NEVER to buy from Iolo and when my subscription to System Mechanic expires, I will find a more reputable/helpful company to deal with.

Customer service sketchy at times
I've been a Suppport.com customer for many years. But since it became Iolo, service has gone down hill. I bought the VPN program and the program works sometimes. It's been out for 3 days and I haven't been able to get anyone to fix it. I call at 3 am and I'm on hold for over 30 minutes. I speak to a bot on their website with the promise of a call back, which never happens.

Customer service bad, program not as advertised.
Charged my bank account to renew the service after having closed the account over a year ago. My account didn't even show up enough to log in or search for a "forgotten password" When I attempted to sign up a new account to address the fraudulent charges, it said that email was already in use. Contacted the online rep who was rude, condescending, mocking and basically told me to cry to someone else. Customer service is a joke, the program doesn't work as advertised. Getting ahold of customer service took 4 hours of sitting on the phone after the negative response from their online chat. Program bogs down the system, and caused problems in the registry. Worked poorly with Windows 11. Do not recommend. Total nightmare

Hello Lord Brae,
Thank you for taking the time to leave a detailed recount of your experience. I completely understand how frustrating it is to deal with an already-annoying billing issue and then receive poor support on top of it.
The support experience you described is certainly not the level we want to provide to our customers. Rest assured, I’ve taken your comments seriously and will take steps to prevent this from happening moving forward.
I’m interested in hearing more about what happened. If you’re comfortable sharing additional details, please contact me at reputation@realdefen.se

Hi Penny,
I’m really sorry to hear about your disappointment with the new version of ByePass+. What you've highlighted are completely valid frustrations, and I understand why the change feels like a step backward in usability.
At the same time, I truly appreciate that you’ve been with us for so many years and care enough about the product to speak up. Thank you for your continued support, and again, I’m sorry for the trouble this has caused.
Rest assured that we are committed to delivering a version of ByePass+ that exceeds the previous iteration. Your feedback will be shared with the product team, but if you'd like to provide any additional details, please feel free to contact me directly at reputation@realdefen.se.

Shady practices
Shady practices. This is the company that sells Iolo System Mechanic. I have previously turned off autorenewal in the past and I keep getting billed every year. There is no way to delete my credit card info from their site. In addition to that the software license is good for 10 devices is really only good for 10 activations. So if you uninstall and reinstall that counts as 1 use. I have just been auto renewed for $80 and cannot even use the product. To make it worse I had originally purchased my key in 2020 and have not received a new one upon renewal. To top it off customer support is also telling me they cannot remove the no longer used activations from the account.

We’re sorry to hear about your experience, Walter. We understand how frustrating it can be to face unexpected renewal charges and activation issues, especially after previously turning off auto-renewal. That’s certainly not the experience we want for our customers, and I truly appreciate you taking the time to share these details.
I’d like to personally review your case to ensure your renewal and activation concerns are properly addressed, including helping to resolve any billing issues. Please reach out to me directly at reputation@realdefen.se so I can look into this right away and work toward a solution.
