Who called from 2120004826

Always calls and never leaves a message. I have never answered it because  000 looks weird to me..

never leaves a msg ....damn telemarkers

Have received calls from this number a couple of times. I do not answer these because of the 000 prefix. No messages ever left.

Got a call but no one said anything.  Why would someone do this?  Do they have nothing to do at all?  Must be 1 short of a 6 pack or something.

I got a call from  1-212-000-4826  when i asked them where they got my number they hung up.  automated asked about lowering your credit card interest.....i do NOT have a credit card.
