Can't close Premier Account

I have been trying for over 2 weeks to close my Premier Cheaque Account without success. I've been to the branch twice and on every occasion, I'm told the account can't be closed because they is a pending transaction on my account of R32 and a pending refund of R16. Nobody at the branch can tell me what these amounts are for or who the merchants are. They told me to contact the Premier Desk to get that information, which I did. The Premier Desk told me that those pending transactions are virtual card transactions and I must contact the virtual card desk as they can't access those pending transactions. I did exactly that, and the virtual card desk told me that they cannot see those transactions; there are no pending transactions.

Is this what happens when trying to close an account at FNB? They fabricate problems? When I checked my account this morning, I incurred additional charges. This could have been avoided if my account was closed as requested. I mean seriously, those are small amounts. I don't care about a R16 refund!!! I just want the account closed immediately so I don't have to inccur charges on an account I'm not even using. Pathetic service from a bank who claims to be the best!
