who call me?

this number is always texting, and causing problems. I dont know what domain number this is but it's from an instant messanger

calling from Customer Affairs & Business Regulations, they claim to be a law firm. They told me my ssn was in a lawsuit that I took out a loan from Cash Advance American and I had three accounts of check fraud, theft by deception, they have all m person information. Wanted me to fax them my license and debit card information so I can pay back the loan. They were very rude and sounded either Indian or Middle Eastern. I have never taken out a loan or owe any one,

calls every other day, 2-3 times, for last 2 weeks, does not leave message

I bought a Mighty-Fixit online, and started to get calls. 3 calls, then I called back. He answered on the first ring with my name. He tried to get me to take gas coupons upon trying something else, I said NO, he said thanks and hung up...

Called my cell phone. Hung up when I answered.
