Until very recently, it was the same for me. Stuck on sub-3 meg whilst streets either side were enjoying their upgraded cabinets or Virgin Media superfast (they never cabled our street).
They FINALLY upgraded my cabinet - over a year and a half after enabling the exchange - and I was on it quicker than the tax man on an incorrect self-assessment.
Word of caution - check the Openreach Superfast checker frequently. Someone I've spoken to was connected to a cabinet which was upgraded - but closed to new customers the day FTTC was enabled on it as Openreach hadn't provisioned enough capacity. So, for about 6 hours, they could have technically ordered it... But missed the window. They're still stuck on ultraslow broadband.
