Call Microsoft SG or which region you registered you the account or you just cancel your CC

silver only allowed to u to send msg and downloading from marketplace

while with gold + u can play multiplayer online

So what i heard is true last time, if you block CC means you can't activate the same account again?
Now your only choice of logging to Live again is new gamertag i guess. You should have call to unsubscribe GOLD ma last time.

It's a painless process unlike when i need to cancel my mobile network, i need to write letter then post to them

^Your cc is unauthorized but its for Microsoft point only right? Did you subscribe to Xbox live via CC? If yes it should be no problem.
I only know there is region control for CC when trying to purchase Microsoft point. (but then sometimes the region control just magically dissapear)
I think someone here mention before about using skype, you need to top up point to use skype though. Anyway i don't think you can subscribe under the same account again once it's blacklisted, the guy in evilavatar.com tried to do so but failed miserably after calling them.
You can still try if you want. If can't call SG you can try other region, i get my Microsoft Point refund from UK Xbox Live customer service although my account is SG one.
Looks like someone is happy now

hey guys, i log in with silver account and found that whole market place is gone.

Is it due to "silver" or maintenance from MS?
