FNB bad service

I tried closing my account with FNB on 30 September 2017 and was told that the imstruction will be sent to the branch where I opened my account. This was not done and after numerous attempts to call in to get the I decided to go to the branch which is 1000km away from where I currently stay (East London and now currently stay in Johannesburg) and found that the branch has since closed down. Through all this time the domaint account is incurring charges.

I managed to get the call centre agent and was informed that I am under debt review since is not true and that is why they cannot close the the account and I should contact Transunion. I have a live report from Transunion and there is no such listing. When I explained this to the agent I was advise to hold as she was contacting the bank's credit department and I held until the call was dropped.
