Not what I expected

Hi I'm Anastasia, Old Mutual consolidated a loan for me on the 15th of May, using the incorrect reference, the company that should have received the money on the 15th of May, has to date 'not received the refund' as a result they debited my account with another R3000 on the 27th of May. I've been back an fourth with OMF to get the proof or to 'link up the payment' with their head office, it is now the 13th of June an I'm still without my money. When you go to the branch, all they say is 'we'll check the system' an follow up, but nothing is being done, no phone calls are made to prioritise this. I even went on wednesday, they 'logged' a call with some person at the head office an the SLA time is 2 working days, I was called in on friday for absolutely no feedback! Totally ridicolous! All I want is that you sort out my proof of payment or link up the payment that you guys messed up,so I can get my money back!
