Any advice welcome.
I have just received a bill from British Gas for £101.05. Problem is I'm not their customer any longer. I called on 2nd May to be told the system is down, no help available and I when I called back got stuck on hold and after 15 minutes got cut off

!!!
So called again, got thru and was told they would call me back, Oh no they didn't !! So today I finally get thru and I'm told this was an oustanding amount from 21 Dec 2006 to 11 May 2006, before I switched to Atlantic Electric and Gas. Only now have they sent me a bill???
Please advise on best course of action, surely they can't just pitch up with a bill for £101.05 a year later and demand immediate payment can they ??
