GROSS INCOMPETENCY and lack of customer service

On the 30th of April I accidentally transferred R2000 from my cheque account to a Discovery account which has not been active for several years. Since then I have made several calls to both Discovery and FNB and received numerous reference numbers. The last call was on the 16th of May when I was told that nothing had been done about the call that was logged on the 3rd of May, but that the matter would be escalated to management immediately. Later that afternoon while I was driving, I received a call from "management" informing me that I should check my statement since the amount was already paid into my account on the 3rd. When I got home and checked my statement, I realised that the "management" member just saw a deposit of R2000 on the 3rd and WITHOUT NOTICING THAT IS WAS FROM A COMPLETELY DIFFERENT SOURCE, called me with an attitude and informing me to check my statement.
