Not Earning Credits - No Monthly!?

Ok so i just earned the monthly, and i got all the credits but after shutting off my xbox and turning it back on i didnt earn the credits im actually down 17k credits which means i completed it but lost the credits… I am seriously pissed with the amount of issues with the online play. i worked hard for the monthly to find out i dont get it…

did you make sure it saved?

i did indeed. cause i played one game after it and than shut off my xbox because i was moving it to my living room. Debating just to not play the game anymore.
