I just got all of my points back today, and my score took the hit last Friday. Yesterday, I called SM and the lady told me that SM had just gotten my dispute letter and sent the correct info to the credit bureau. So if anyone wants to move things along, I'd recommend doing a dispute letter.
SM also offered to mail me a letter regarding the whole incident in case I need it. I told them to go ahead and send it so I'll have a record of it in case something fishy pops up down the line. SM told me that if I needed to have my credit check within the next 3 - 6 months, then I should get the letter. I don't know if that means they won't have everybody fixed until then, but I recommend getting a letter just in case.
The customer service rep also asked if I'd like her to lower my SM monthly payments or lengthen the term of my loan. I told her "JEEZ NO!! Don't change anything else about my loan while you're in the middle of this mess!!!" lol I guess that was their olive branch... But if you COULD use a little help with your SM loans, and you've been hurt by this fiasco, I figure you're in a good position to negotiate with them now.
