Keeps calling, i keep missing the call. I call back and no one answers, goes to a sprint pcs mailbox

Recording asking for a person who has never resided at my residence. This has happened three times in a row (at night). I imagine it is a collection agency, but am just guessing. "Press 1 if you are.... Press 2 if you are not .... I pressed 2 SEVERAL TIMES and go a person whom I told to stop harassing me. I'll be interested to see if that worked. 12/12/07

213 is an area code for Downtown Los Angeles, California. Don't know anyone from that area code so I let the machine take the call. No voice mail was left.
