Scammer posing as Discover Card

Victim Location 38006

Type of a scam Credit Repair/Debt Relief

They called to let me know I available to lower my interest rate on my card, they asked me to verify my card number, even the number on the back, and also asked if I had any other credit cards which thankfully I did not give them. But I called the real discover and they said they wouldn’t be calling me to lower my interest rate, so I knew then I gave a scammer my whole credit card information, but the scam is on them cause they cannot use my card, I cannot even use my card.
