New gamertag will not update on messenge ...

I recently changed my gamertag from Jungle Massiv to Cobruh about 3 days ago and when I'm signed into messenger on the Xbox 360, it still says that the gamertag is Jungle Massiv! It shows as Xbox 360: Dashboard (Jungle Massiv) It should update and say Cobruh in the brackets.

I know this because I looked at it on my other msn account. I have already tried signing into web messenger. How do I make it say 'Cobruh'?I've also tried recovering my account but it still says Jungle Massiv! :xI've already asked this on xbox.com but still no replies and the thread has been there since 5:02pm GMT! :?New gamertag will not update on messenge ...
Still nobody replies :|
