Most pathetic service

After making the required payment to my credit card at the end of February, I received a message reminding me of my payment due. I thought seeing as it was only a day or 2 after the payment that it must have been an automatic notification. Then a week and a half later my account was debited again for the same card. It was the last of my money to get me through the month. I've been trying to sort it out for 3 days now. Today I phoned the call centre 6 times and spoke to 10 different people. They were all utterly pathetic. They wait for me to explain my whole situation to them, only to just put the phone or transfer me to some random answering machine just to start again with another agent. I don't know why I expected anything better. All I hear about FNB is the useless client service!!!
