No they don't get your number from stuff like that. I know I have never posted my cell number anywhere online and they have called me several times.. as well as another family member's phone who has never posted it anywhere.
This # 201-221-3014 is a fraudulant call, in that it first states ,and
I quote: The warranty on your vehicke is expired, Unquote) Note the word
vehicle, (what vehicle?) When you question these pettyfoggers they will tell you that they are selling vehicle insurance! Report them to your Attorney General, in whatever state you live!
I got off work the other day and my cell said 6 missed calls- all from this number. I answered it one day and it was automated, so I couldn't tell them to quit calling me. I tried to call them back, and the recorded message just said "you are calling from.." and then told me my phone number.
Every few days or so I get tons of calls from this number for "car warranty". I had been getting them on my home phone, so I was shocked when they started calling my cell phone too. (I have a local carrier, Plateau, by the way).
