Who called from 2153573375

All the numbers are refered back to 214 257 3375 which is a Verizon land line...If you live in PA call 18004833000 to complain. This information is given to me directly from Verizon themselves.

called numerious times over a three day period and would not speak.

Called from 215-364-9789, but upon return call 215-357-3375 is voice mail number.

I'm getting the exact same thing on my cell.  I've gotten these calls all times of the day, even at 1:46 AM.  When I answer, they hang up.  When I call back, I get a full voicemail box for the other number.  Does anyone know what we can do to stop it?

I am getting the same calls and so is my b/f - anyone figure out what the hell this is?
