I have called LP. They do have a record entered in their computer that they have received my documentation for missing postings. My brother called in also and they are "working" on his. He sent his in about 7 weeks ago. So it appears they take about 7-8 weeks for LP to get to it after the docs arrive. But at least you can check to see if they have recorded that documents were received.
Not sure how long after posting the miles are actually posted to the account.

My question to the board: Has anyone been contacted by LP with them refusing to post a documented activity?? If so, what was the reason and did you get it fixed??
