I had a complete nightmare with British gas before we moved here. Then we came here, where the gas is ready for when the oil boiler breaks but not connected yet, so we don't have gas at all. They tried charging us a standing charge for it, and when OH rang and complained the guy said I see your point, I'll switch you on to a tariff with No standing charge. Goes away and comes back only to say they don't do one so his advice is to change supplier.
There is just no common sense any more.
