Being shunted from department to department

Hi, My Premier card has been declined for several transactions because of possible *****. I confirmed that it wasn't *****, but legitimate purchases, but my online transactions are still being declined. I have tried unsuccessfully to sort this out with FNB call centre - but I get shunted from one department to another, wait on the line, get cut off, start again and still no resolution to the problem. I just want to use my credit card as I used to be able to. I really don't have the time to be shuffled from one department to another - just please resolve the matter.

Thank you
