R5000 MISSING IN MY ACCOUNT

On the 25th of January 2016m I went into a Branch in Rustenburg to do an internal transfer to STD BANK, On the same day I noticed R5000 was deducted from my Account and after trying to have the matter resolved I was told the last person that Logged into my Account was this Mrs Chetty with Employee number ***. All I want from ABSA is to refund my Money I don't want to hear any stories because some of us have families to look after and money cannot just disappear from our accounts. If this is how ABSA is handling their Platinum Banking Clients then I will have to go to a Bank that I have never heard any funny stories about and that bank is FNB Bank, I want to stay loyal to ABSA but all I want is my Money back into my Account with in 72hrs or I will take this to the Media as I have proof of all what I'm not happy about and I do have friends who are working for media Companies and I don't think ABSA will want its reputation be tarnished by one single employee. I have my Bank statement and Print out from the bank with details of the last person who logged into my Account and I will take this as further as to the Banking Ombudsman
