They didn't say anything when I answered. I said "hello" several times, It didn't disconnect, they just didn't talk. By the way,it was my cell that they called.
I got a call from this number on my cell but missed it. I called back and it said GMC Credit Services. I don't have anything financed through GMC, so no idea why they called.
I also received a call from that same number and they said they were GMC Credit Services. When I told them I have no affiliation with them they wanted my social security number before they would tell me why they were calling.
