Discovery refuses to pay me MY OWN MONEY

I made the mistake of transferring funds into a non-existent account after my card number changed. I then phoned discovery card and asked to have the funds re-allocated to my new card. After sending two proofs of payment, speaking to 5 different consultant, sending numerous emails and waiting for more than a month I still have not received my money. Every consultant promises me that the money will reflect within 5 working days but after waiting the 5 days the money doesn't reflect and they don't even have the decency to call me and tell me why. So then I have to call them, just to hear the same promise and be disappointed again.
