Incurring cost

I have a stand alone Petro card which I seattled on 7 September. On the same day I phoned Fnb call centre and asked to have the account closed. The assistant took my details and assured me the account will be closed.<br> <br> The next day the monthly bank cost for this account went off along with intrest, on 10 September I made another payment of over R100 to seattle all the amounts and ensure my balance is zero. <br> <br> On 9 October I noticed that the monthly admin fees went off once again for the account I've requested to close more than a month ago, and also settled. <br> <br> The service I receive is very poor, I made a simple request for my account to be closed, and can't understand how this is possible? <br> <br> Bank fees are already high as it is, now the bank is charging me for an account that I've requested to close?? <br> <br> Which other channels do one follow if the channels provided are not effective?<br> <br> I want to have my account closed! Also reverse the bank fees.<br> <br> Regards<br> John
