Capitec/nedbank incompetence and failure to assist

I was supposed to have recieved funds from abroad, there was an unfortunate error in the beneficiary details and this caused the payment to be unsuccessful. Fast forward a month I am still in constant contact with capitec forex to try to get the money returned to sender. They have escalated quite a few times and the corresponding bank(nedbank) have not even once rep**** to capitec apparently. After waiting a month and constantly trying to get this money back I still have nothing to show. If anyone out there can help id be very grateful. Ive spent over 100 minutes of my mobile allowances and sat on hold for many hours. I have been hung up on and told multiple times that i woukd be contacted back and nothing. This is mildly infuriating as all i keep hearing is that they will escalate. But this has no effect so far. Please help
