FNB ********** transactions

FNB is trash. A ********** transaction that I know nothing about was made on my card and I reported that. I told them I want my money to be reversed while it was still an outstanding authorisation but instead of chargeback from they made me sign ***** reporting forms saying they will "investigate the incident" and get back to me. Till this day I haven't recieved any feedback or refund, mind you all this happened on the 12th of December. What's worse is that I saved that money for my registration fee for University.... I want to close my account but they keep telling me I'll have to close it where I opened it (that's another province). I'm really sic and disgusted at FNB, if it's not ********** transaction on your card it's the EDO ********** debit orders. I want nothing to do with them anymore, I just want my money back and close my account.
