Unacceptable Discovery Credit Card Waiting Period

I am beyond appalled at the service I have received regarding registering and receiving my Discovery credit card. A process that is meant to take no longer than 10 days has taken me over a month (I first registered online on the 15th of April.) I have called the call center over 5 times and every time there is a different excuse as to why my quote hasn't been processed. My last phone call was last week Thursday and apparently it takes 3 working days for the courier company to call, however I have heard nothing. I have been a customer with discovery for YEARS and the fact that I have to wait over a month for a credit card is shocking!!! Who do I need to speak to in order to get this process right because I really don't think it is fair to take it out on the call center employees. Come on discovery I am literally giving you my money, get your processes right. it really shouldn't be THIS hard!!!!!
