Refund Paid to Incorrect account

A refund that was paid out ,was paid via EFT to an incorrect account not belonging to me. I enquired two days later as to why refund not reflecting in my account to here that it was not my account. I was sent paperwork to rectify the incorrect account details, which was changed the following day 9 Nov 2015 (EFT Date). However discovery did not reverse the EFT and after further enquiry the customer service centre said it was now too late, that they can only issue me with a letter that I have to take to my bank and they will have to assist me. Standard Bank has now informed me that they are not able to assist me and that Discovery has to reverse the transaction.<br> It has now been almost a month and after many calls I have done everything that was expected of me but it is now ridiculous, the run around I am receiving after my own money is frustrating to say the least.
