I was contacted in the past by CG Services for student loans, but I am wary of all callers of this nature. I was almost scammed by an actual attorney trying to collect. I think there's a bounty fee for Dept. Ed. collections, so all kinds of jokers jump in.
They leave suspicious messages, call all the time. I don't answer.
Received a call on landline asking for former employee. He said his name was Timothy and when I asked what the call was regarding he said it was personal. He then said he assumed he was calling (my husband's name) and that he'd been told to contact employee at this number. When I asked again who he was he said, "I already told you. Timothy." I ended the call.
This is a number for GC Services, which is a collection agency. I think they mainly collect for the Dept. of Education for student loans. They have calling centers all over the country, so this is just one of many numbers they might call you from.
Called early in the morning asking for my ex from 5yrs ago. Identified themselfs as GC Services, i asked what it was about and they said it was personal. But I know he has student loans in collections, so i'm sure that is what it is about.
