Terrible service

Still waiting for a reversal of R1500 for something that was a fault on fnb's. After having to fill in reversal forms for something that I nor the shop i purchased from did anything wrong. Merchant can tell my first 2 swipes were declined, I don't have the slips for it but you can obviously see this. Nobody keeps a slip that says declined because nobody assumes that fnb take your money. I did even complete the given forms for my money back, still waiting. Terrible service, very unpleased.
