Dealership question, rebate screw up
I got a call from my dealership. They said my rebate got screwed up and I'm owed $300. Great right? However, I need to sign some form to get it. Not sure what it is yet? Unfortunately I'm really skeptical of this dealership just because of the way things were handled when I bought the truck (long story, misleading info, dishonest etc). I was just curious if GM backdated any rebates from 2016 that I should know about (I bought the truck in Nov), or if there is potentially a larger rebate left on the table in case I sign some form saying I am no longer eligible for future rebates etc? Thanks.
