Who called from 2012213014

This is an unknown phone number.   I looked at this site that many
people have been disturbed.

Called this morning (cell), busy signal when I tried to call back to remove.

i don't keep track of all the different #s they use but i get frequent calls on my home phone - not my cell like most of you.

Don't know this number but it was appeared on my ATT cell phone.

i have been getting calls on my cell phone at least 10 times a day from 15 different numbers and every time i look them up its the same thing auto warranty, and since i just renewed my warranty through the manufacter why would i need to do it through them, this is getting really anoying, how do i make it stop?
