No internet. Network access : Blocked

My Internet went down 9 hours ago.

I can connect fine to my hub setup on a Web browser but the info page shows "Network access : Blocked" and my hub status page shows "Internet (Access denied).

I don't owe any money. I've done the usual power cycle. I've even defaulted the whole thing and started from scratch.

Virgin are telling me it will be 3 DAYS before I can have an engineer.

Somebody at virgin please explain why the hell is my internet access denied
