It can't be regarding a warranty cause I don't have a car. It's ok though, I have ATT Smart Limits on my cell which blocks up to 40 call. My house phone has a blocking feature when I bought it. So, I'm good.
Called my cell phone. I don't answer numbers I don't know. I don't give out my cell, other than to friends and family. We have a separate land line for our home with a different number. Not sure how they got mine?
