Who called from 5014173000

Called our friend mat in class then called me

Security System Sales Call from this Number. I blocked it.

Call but don't leave message. When call back say none working number or when I answer they just hang up. Call all the time.

I have rejected a dozen different numbers from this same company for a year. Still they call. It wont stop. All hours, day or night. My reject list won't stop it because it's called from a number one digit off the last called from. I'm thinking a vacation day to Kansas. (I know they're address now) I'll make them #@$! they're pants!

No security system. They want to return $350 to my credit card because business is closing and I have overpaid. Sometimes a "manager" then calls. Scam!!  have called from multiple bogus numbers. I don't answer.
