Who called from 9498910987

GMC Credit Services. Collections company.

This people are very stupid, They don't even answer when you say hello.

This number calls me three to four times a day.  When I say hello, there is never a response.
When I call it, someone pick up, but says nothing and hangs up. Annoying

this number keeps on calling and hanging up, can someone please shut them down for good.

stop calling.  your first and final warning.
