Bad Service

I tried to use my debit card to withdraw funds at checkers, however at checkers the card declined and the funds where out of my account. I began to call FNB on the 9th to see what went wrong they informed me the funds where hanging and needed to be reversed. I spoke to many call centre agents and all of them were so rude and unprofessional. they all gave me many turnaround times and didn't know what the hell they where speaking about. to this day I still have not received my money back and was told they still waiting for authorisation from the debit card department that is now taking forever to reverse the funds. FNB is a horrible bank with the worse service ever.
