Me llamo cuando nada tiene que ver con ninguna actividad relacionada a mi persona es fraudulento este número y es una estafa todo lo que con este número realizan

Trans World Systems....but I do not know the nature of their business or anything about them.

These are criminals pretending to be debt collectors, most likely off shore.

I answered 1 call....said hello, no sound but open line.   I said hello again and nothing. I said "speak now or I'm going to sue you for harassment", they hung up!!!

This number call me for to much times. No body answer.
