I have contacted Discover card several times in regards to a charge that was made by a Hotel that admitted to me that the charge was a mistake. My husband sent the email that we received from the hotel where they admitted that the charge was a mistake and we should get our money back. Discover says that the matter was resolved weeks ago but as you might have guessed, the money has not been credited to our account. I contacted to find out what the problem was only to be informed that they have a technical issue on their end. Well my problem is that they definitely don't have any issues with other charges, other refunds and most important getting their money from me. My conversation with them simply put was, don't call us, we'll call you. What a joke! I think it may be time to do away with their credit cards and find better service elsewhere.
