Correct to all of those who say call at the end of the promotion.
I called over 2 weeks after the end of the last promotion, not to inquire about the previous promotion for which I did not meet the goal, but to get nights stay postings for the current Megabonus promo corrected.
I told the Plat CSR that it was unfortunate that my 14 nights from Jan 17-31 didn't count for either promo and that I also mentioned that I did not meet my goal for the previous promo. She said wait a minute and put me on hold. Came back and gave me 5000 points for 3 stays. They are aware of the different offers and I didn't say anything other than I didn't meet the Megabonus goal.
