Cell C data useless

I currently use Cell C as their Giga 20 package was the best value I could afford.<br> <br> Mainly I play World of Tanks on the EU servers and everything was fine up until roughly 8 months ago when I started having trouble logging in to the game's servers.<br> <br> Now everything else works fine, email, browsing the web etc, even worldoftanks.eu works fine. Just logging in to the game is a problem, but it's not on the game's side as when I switch to my Vodacom I have none of these problems.<br> <br> The only way I can manage to connect is by disconnecting and reconnecting the phone's data connection until I can login. Sometimes it is in a couple of tries, other times it grinds my nuts.<br> <br> It all seems to come down to either the IP Cell C assigns me or it's a DNS propagation error.<br> <br> Either way I am getting seriously aggravated with this, either you sort your network out or you cancel my contract at your expense so I can move my business to a better provider.<br> <br> BTW, this contract used to be under Nashua Mobile, it is now under Autopage. And don't refer this problem to Autopage as this has nothing to do with them and everything to do with your network service
