My cell is on the do not call list, also since it first came out, I've even double checked a couple of times. (I still get those toner hogging dumb tele-sales faxes....)
The number that called was (559) 266-6306 on 12.20.12. It ends up being Coverall cleaning, whom I use locally in San Diego. But the call came from there Corporate office in Fresno. My company purchasing people gave out my cell # instead of my office number. I still don't take calls from people I don't know, if they really do want to get a hold of me they can try my office # or my email if they are known to me. I know there is very little privacy out there but I try it keep the little I can. They did call my office line that how I found out whom it was and I asked where they're out of (Fresno) matches the call I got 30 seconds earlier.
Coverall is a franchise janitorial office cleaning. I've had my cleaning service with them for 5 or 6 years. But since its a franchise its only as good as the cleaning person you get.

Another annoying telemarketer!!!!!!!!!!!!!!!

This outfit of crooks change their telephone number every once in a while so you do not find the reports of their criminal behavior using their previous numbers. I got a call on my unlisted residential number that has been on the federal do not call list since it first started. Their phoning me indicates that they are federal level felons.
