Worst customer service

I have been trying to close an account for months now. I paid off my vehicle and had an account linked as it was an Access Finance account. I went to the Cresta branch and was told they could not help me, gave me a number to call which I did and was again told they can't help me, but the account will close automatically as the vehicle is paid off. I emailed the contact email address and never had the courtesy of a reply. I am still being billed a monthly ledger fee on the account and cannot get anyone to close it for me.
