Jacksson Vadera from Ayr office was exceptional- thank you

I was very fortunate to be under the care of Jacksson Vadera from the Ary office during my account opening process. I struggle with forms and numbers and he was incredibly patient and went out of his way to be as helpful as he could. He was so professional and courteous. He also was very diligent and picked up errors on my form that were very subtle but significant. Again, he showed great patience and enabled me to fill out the forms correctly. I do find the castle water systems quite clunky to use. I feel the process could have been a lot smoother. If it hadn't been for Jacksson's help I would have taken my business elsewhere. Hopefully now it will all be plain sailing. But I really can't thank Jacksson enough. He is a credit to the company.

initial experience not great but ended up good

initial experience not great , although we were dealing with my debt there was very off handish communication and huge charges . Finally someone who listens Josh Sturrock listened to my concern and actually arranged a refund of what i considered grossly expensive and unfair charges , Thankyou Josh You would have got a 5star if it was just you

I spoke to Robert - I was closing the account as we have just sold the property.
Robert took my final meter reading and advised me of the balance on our account, which was the reason for my call.
