Right have changed my card on account as last one expired, now it wont allow me to buy anything so took it off account put it back on still didn't work.
Then used different user name with different card and PayPal account still didn't work, tried mine again still didn't work, what do MS support say "get a different bank account" even after i checked with them and they said its MS end after running checks. Spent half hour disagreeing with MS saying even if i was stupid enough to do this whose to say it would work after trying different methods.
There spending a week to investigate, now only reason i wanted to use it is to get family xbox live gold which is cheaper and you cant get it any were but live.
Also no getting error 80153021 code on xbox which is pe-paid code error i believe why would you get this on a card ? GRRRRR.
Will keep people posted when i do find out what problem is as its not uncomon a problem after doing a bit of reserch.
