Who called from 2675355502

I got calls back to back from this number this number and when I answered they hung up. I called it back and it said "Good bye".

I called this number back when seeing that I missed the call earlier today.  The recorded voice says "this number is unallocated."

how do these morons get my cell number!

They didn't.  They have a computer that generates numbers at random.

Just got this call today. I've had these clowns call me periodically offering a free home security system. This number is from Philly, but they call from all over. For example, I've had the same call from an Oregon number and they claimed to be in Orlando. These idiots steal number logs from cell companies to try to trick you into giving out your financial info. Just ignore them.
