Complaint dedicated to FNB

I decided to pay off my credit card and was informed that I paid in excess, good news that turned into a nightmare after I asked them to deposit the excess amount t into my Gold Cheque card so I can pay that off too(settle it and close) . 1stly the Gold Cheque card was blocked for both credit and debits - ok if I owe you how do you expect me to pay you if you've blocked the credit facility (EFT and Deposit bounce). I’ve called I’ve been to the bank I’ve sent emails in vain – pillar to post is all I got instead, with a list of numbers and emails – oh and calls to remind me to settle an account I’ve been trying to pay off … Blakes and FNB please sort yourselves out, I wouldn’t be owing you now if you had not blocked deposits into my account in the 1st place. I’m so done with FNB and their credit card ladies (call centre) with an attitude on a platter.
