Money was deducted twice off my account

I bought products at a Merchant on the 1st of March 2015 and the amount was deducted twice off my account.<br> I then went to the merchant an asked them to repay me but they said I must go to the bank and request from them to reverse the transaction.<br> <br> I then got a form from the bank and filled it in completely and faxed it through as that was the only form of communication that they are willing to use.<br> <br> Nobody came back to me to confirm that they received it. I then went in to the Menlyn Branch and asked them to confirm for me that the form was received, which they did and according to them it was still in process. I accepted this and I waited the required 60 business days (about 3 months) for them and when I called them nobody was able to help me and the disputes department does not have a clue what I am talking about. I spent about 3 hours on the phone that day trying to get help.<br> <br> I then got a hold of somebody and they said they will help me, I have sent emails and called multiple times after their first reply and I have received no feedback as yet since then (about 2 weeks ago).<br> <br> My has not been refunded, because of an error the bank made, and it has been almost 4 months
