OP when did you update your sub? I updated mine a few days after Gears Of War 3 came out witch was about 3 weeks ago. I got the Gears of War pack 12 months plus 2 months. I also bought a 1 month for £2 before I updated to 14 months.
I tried the code i think it took it but i have yet to get my points. I tried again and it says the code was already used. I think some xbox live employee has it out for me, i always get shafted on xbl rewards. I think my tenure was also messed with, it says
3 now, it was 6 >.>. Took me 4 months to get my xbl rewards banshee avatar item, had to scream scratch and beg to finally get it.
