FNB refusing to give money back.

On the 30th of July I transferred money by mistake into my revolving loan account instead of my saving pocket. After numerous emails and phone calls to the call center, they told me that I need to go into the branch to have this sorted out. I went to Galleria branch on Wednesday, 8 August. The consultants made phone calls and sent an email. She told me that everything was done from her side and that my money would be in my account within two working days. Today is the 17th of August and I am still waiting for my money to be transferred back into my cheque account. This is MY money that FNB is claiming- I have accounts to pay and clearly customer service is not a high priority for them. Every single person I spoke to at the Call Center sent an email for the money to be reversed back into my back account And yet NOTHING. FNB is becoming as badly with their customers as Vodacom.
