Credit card

I wish workers at Standardbank that work with my account will wake up! Like in the pass I paid up my credit card in full just to receive a statement that there’s still an outstanding balance. I reviewed my statement and see that they charge me over R160 for credit cover, then there’s an amount for bank charges and small little amounts that Standard bank put on outstanding budget. Why do I have to pay life cover and other cost if The account is paid up. This is not the first time it happen, I need my account to be rectify and zero outstanding balance. I feel Standard bank is steeling from me. Doesn’t help to call the call centre because I was holding on for so long that my airtime run out.
