Never Received the Card

I app**** for a Discovery Card in 2016 to be able to get the Apple watch. After months of struggle I never received my card and I was never called to inform me that my card was ready for collection or delivery. Accordin to their records they have tried to contact me to arrange delivery which was not the case. I then decided I will try again. Calling them this morning to sort this out because on my Discover profile ot shows I already have a card. I was not able to pass the verification test due to i correct information that I supp****. I cannot remember what I have written down 2 years ago on an application form. I instructed them to make a plan so that I can just cancel the card- thinking that would be easier than to actually retrieve a card. His simple response- sorry we cannot help you. I am soooo frustrated and irritated with absolute disgusting service. A credit provider saying No Thank You to a potential client.
