FNB Private Clients Poor Service

If I would give them no stars if I could.

I am struggling to this day with a large credit card transaction on the 25th of July that was reversed by FNB, (sms recieved) and then subsequently disappeared from my account. I have lodged official dispute forms, proof from the vendor that it has been reversed. I have submitted this more than once. Today again received a e-mail from yet another department, asking for all the same documentation. Every time I call or e-mail I am told the matter is being escalated. I have sent everything multiple times, e-mailed and phoned more than I can count. This matter is still not resolved. I again contacted them today and was told the matter would again be escalated. Laughable service.
