I received my full outstanding points for Novermber yesterday, though I'm still owed points for October?! Very strange. I called MR and they said more points will be doled out in the next couple of days, and if points are still missing after that then to call back. At least there's some movement (for seemingly most people).
For the record I did not receive the postcard, enrolled in only the 5T/5K promo, and have not contacted the FOS, though I did write a complaint letter to Amex when they wrote to bump me onto the 10T/5K scheme. The following week I received the apology letter saying I was on 5T/5K, and the points I've received to date are in line with that scheme
