Who called from 6363739464

I turn off my ringer when going to bed

Just received this anonymous call at 6:37 p.m. e.s.t. They did not leave a voice message.

Received a call on my cell phone last night at 11pm from this number saying it was some kind of research survey or something like that and gave me some 800 number to be taken off their call list. Thanks for the posts with the 800 number since I had no pen and not awake enough at 11pm to write down their number.

This number be call I think it a bill Collector of some kind
