free gas card

Lady called to thank me for paying my credit card on time and that there was no current problem with the card. She was calling to offer me a $250 gas card. All I had to do was verify the last 4 digits of my credit card. However I had no idea what credit card she was talking about so she named off 4 numbers and said well maybe its a debit card. I'm not stupid we all know you dont make payments on your debit card. Well I told her that I didnt have a credit card with those numbers she said sorry I will remove you from our list. She had an english accent and you could tell she was in a very noisy office or room.

I recieved the same phone call and it was the exact same situation except all the people had an easter indian accent. when I asked to talk to the supervisor they said their company name which I do not remember so I called my bank and they said do not give them anything.
