This number has called my home several times without leaving a message. Not sure what it is about. I refuse to call them back. Next time, I may just hit fax accept, and maybe they will stop calling me. As one other person reported, it is ILLEGAL for them to contact anyone except you if it is regarding a debt. According to the fair debt practices, they are not allowed to contact anyone but you. I didn't get any information on the caller id except for the phone number. Hope that this helps someone!
A lady left a message on my machine asking to call her back at 866-735-1713 and said that it was important. They called without any introduction. Probably a collection agency.
called and didn't leave message. called by with *67 and someone answered as GC Services. I just hung up.
Their website (I think): http://www.gcserv.com/
