FNB very Incompentent

Good afternoon, I just want to make an enquiry regarding closure of an account at FNB. I have been with Capitec since end of 2016. On the 10th of June 2017 I have paid the Credit Card and my debt at FNB in full at the branch at President Hyper Building in Krugersdorp. It took another 9 months to receive a confirmation that the Credit Card account is closed. That day I have asked the teller on duty to close all my accounts at FNB. I have received last week a call from your Collection department to inform me I owe R2 570.00 to FNB, when I asked her what it is for, she said she doesn’t know I must go to a branch and ask them. Which I did on Saturday 17th of August. The lady told me it is the Overdraft account, interest on interest for another 2 years!!!!!! My questions are: Is there anybody managing the accounts? If they could trace me now, why didn’t they contact me sooner? At least 3 months after I have paid up the account. Why leave the account open and not close it as I have requested? Why leave it to accumulate for more than 2 years. You should send your customers on a course to know how to close an account with your bank. I am 61 years old and trying my best to get out of debt before I go on pension but I give up……… I am very, very disappointed in the management of FNB and going to report this case to the National Credit Regulator. We we send them 6 emails but nothing this is the weakest bank that we delt with so far, we chenge banks because of the poor service we received from this bank. No customer service exist, no pride in their sirveses, all we ask is to tell us what is going on and now Blake and assossiates is also involved. Stay away from FNB
