Who called from 5204224166

this number calls me all the time about re-newing my car warranty..funny thing is I don't own a car..

Ah, yes. The self-proclaimed "supersmart" wields her ad hominem attack weapon. Pathetic loser, you are.

Unwanted call to my cell phone. Does the Do Not Call Registry mean anything?

Means calls from honest telemarketing stops, not crooks, bill collectors, fundraising, surveys, or political calls. So the calls you're getting aren't likely to be from honest telemarketers.

No message left. Called twice. I refuse to answer unknown numbers on my cell phone.
