Who called from 6136996612

8:30 p.m. on a Sat night. I called the number back but no answer time to block em!

I keep getting calls from this individual and I don't answer Because I dont know who they are. I don't want to either!!  That's long distance that I don't need on my phone!!

this number called twice would not answer

The person asked irrelevante questions saying that it was a research company.  Normally I don't answer this kind of calls.

This person is Sick, I get calls in the midnight and when called there is no response. I get like 5-6 calls a week from same phone number.
