Who called from 3869446331

This number just randomly called my cell phone. I have never heard of this phone number. As soon as I picked up the person on the other line hung up.

Same here.... getting tired of it. Seems related to the same calls I got yesterday from 386-944-6100.

Same here. They've called me probably 10 times in the last 3 days. Do you know if there's any way to get them to stop???

I answered the call.  They claimed it was Verizon checking on the service

They just called me at dinner time, on my cell.
How can we stop these incessant calls all day every day including Sunday?
I have an answering machine so they have to speak ir they want an answer, and then I can tell them not to call. But almost none ID themselves. What's the matter with the telephone company that they can't stop them in these days of such high tech.
