So I got into the mileage game a few months ago, and since then have been following this forum religiously hunting down deals and miles/points; most of the time things post within the 6-8 weeks like they say, but in some situations even after this period the miles/points still have not posted.

What are some tips for following up with different companies and airlines for missing miles/points, or does anyone have a certain template that works well for getting results? Is there a preferred method of communication or contact people that work best? (I use SM for credit cards, but that option doesn't really exist for other places) I always make sure to take screen shots of different promos I sign up for too so I think should help.

Any advice would be great!
