got a missed call and voicemail from this number, said I need to contact a person at Ally Financial.

got a call from Kent at this number. He said, so and so has listed me as reference to call. lets just say I do not know these so and so's. Kent wanted me to call an 800 number he provided.

It is a collection agency.  Used to be GMAC.  Have a relative who owed money years ago and filed for bankruptcy, so they think the person lives at my house.  No matter how many times I tell them there is no one here by that name, somehow they still manage to keep calling years later (I guess through the old pass the buck to any agency willing to try to collect).  I know you can collect for every call they make if you send a certified letter receipt but there are too many of the sleazy ones out there who call from all types of names - agencies - still looking for that person.  Life....

I got a call too ,  from  someone named Kim. Said she was an account manager.   Funny  , I don't  remember ever talking to her.

This is definitely ALLY Bank, the GMAC spawned financial institution.  They are relentless and disconnected.  I have spoken to one representative to only have some other clueless A** H*** call an hour later.
