Credit card Cont'd attempts collect debt not owed Debt is not mine Kansas

I am getting letters and phone calls from 'First National Collection Bureau Inc ' stating I owe money from a - - - - from 2007 which I never opened nor did I ever have. They are telling me they ca n't turn me into collections but I need to pay them. They have my social security number and address and it 's terrifying- I have no idea who they are, and it sounds like they just want my credit card information.
