Who called from 2136999156

They have been calling me LATE at night but no one there. This is harassment. Send them to Guantanamo.

Sounds like a telemarketer. I had a missed call and called back. There's a message to Opt Out and be placed on the Do Not Call list. Some story about FCC regulations. I placed them on my Reject List so they can't call me from this number again. Just block 'em out, folks. Problem solved !

Got 5 missed calls from this number yesterday at 6:45ET. Didn't leave a message. Called back and got nothing.

I had the same problem!

Two calls at the same time from this number.  Caller ID says "Service Call".  I've gotten several calls in the past form the same ID, different number.
