Waiting on a refund for over two months now!

I put in a claim on the 29th of November advising that the refund must be paid into account via EFT. 2 weeks later I call in, only to find out that it a cheque was sent out to who knows where!They then cancelled the cheque and requested an EFT into my acc. Two weeks after that I call in to be advised that they dont know what happened, they will request it again. This was the scenario the next three times I called! It is going on three months now and I still haven't received my refund. Discovery employees are so ***********!
