877-698-6807

When you call this number back, it asks for your social security number

Same thing here, they called, said nothing, hung up and when I called back it asked for my user ID or SSN.  I decided to check it out here as it seemed fishy asking for social security numbers.

Number called was unable to answer the call.  I called back and was asked for my ssn. Very fishy operation.

Yes, I got a call, on my cell phone, last night at 6:10 pm.  No message was left, but when you call the number back, it just asks you to enter you SS # and user ID number... um, sorry.. not gonna do that!!!  My philosophy, no message left, must not be important enough for me to call them back.

Mimicing GMAC whose number is 866-698-6807

I just got a call from this number (877-698-6807) and didn't recognize the number so I didn't answer...I experienced the same as everyone else...I called it back and it asked for my SS number.  It was very suspicious so I didn't...I have an acct with GMAC and it definitely does resemble their number, but I didn't remember it being an 877 #.  Thank you VERY much for sharing your experiences so I don't make a mistake...
