FNB does not understand customer service and problem resolution

I have made numerous calls to FNB. The staff from the Call Center to the Premier Suite will not go the extra mile to solve a query . This is not rocket science stuff . I made a credit card payment of R29 000.00 some odd on the 07 August to the Chopra Center the same day the amount was reversed but reflected R27 000 some odd on my credit card. Chopra center reversed the exact same amount. I lost R 2000 some odd on that day and I know the rand did not fluctuate so drastically . Are banks that greedy and ethical that they will ***** every cent from you? I would like to have the R 2000 that FNB took away from me . That is my money and it’s equivalent to theft FNB. Contact me *** Actually just reverse the charges on my credit card .... it’s the right thing to do FNB !!!
