Run a credit check... they cost like 30 bux, but maybe there's some bullshit someone tried to tack on you. Same shit happened to me, someone had a name that was remotely similar to mine, so the collection agency figured I must be the same person (N/m he lived in the midwest and I'm in Cali...). If they did stick you with something that's untrue, give them a call and try to get them to clear it.. might take a while but when you start threatening them with legal action they usually take the thing off your credit.
