Poor Forex Response from FNB

After going in to my local branch and speaking to a call centre agent named Colin who advised me to contact a Mr Annamalay at FNB Forex dept via email which I did at 12:04 pm on the same day Tuesday 27th November I had to phone in again to FNB Forex and spoke to an agent named Renaldo who then walked over to Mr Annamalay's office and spoke to him and ascertained that he will only now respond to my request to rectify a mistake that I had admitted on Tuesday making when I processed the transaction. I requested that I wish to have Mr Annamaly call me within 10 minutes of this complaint log which he failed to do and I am as promised placing a complaint regarding poor service from him.
