Terrible, worst service

I am extremely disappointed in FNB's credit card services. My limit is R1000 and after canceling my credit card in December 2018 I had an amount of R1447 in my credit card account. In January and February 2019 they are still deducting Admin fees and credit card fees after cancelation. The amount of R447 is also not their money as that was an additional amount I paid in once I canceled. I could not take that money out of the account but I could still pay money into this account. The account is also still visible on my fnb app. I have canceled my credit card and want my money back which they have taken for services fees after two months of cancelation. I hate this bank and I will be moving to another ban**** And if there was an option for no stars I would've chosen that option instead.
