Tell them to cancel the card.
I paid the balance then told them to delete the account, not being too polite. I then called and talked to my Visa card carrier, USAA, to ask if they would raise my rates because of that. They told me they don’t play games like that like Discover does.
If you don’t know of them USAA Visa/MasterCard is the best company there is to deal with, hands down.
