After an hour chatting to the "bot" then someone who claimed to be human I got to the point where I was told all tariffs have a standing charge.
I was then told my standing charge was 0.000! Having asked if I could renew on the same basis I was told I could so I told em to get on with it.
Pretty impressed, it only took an hour and a quarter......
Its British gas.
I go transferred to them last year when prev supplier went bump - the tarrif got transferred at same time and was until end July this year.
British gas started off by saying I could not extend current tariff past end of July however after some on line arguing they seem to have agreed to continue it.
I have transcript of exchange with British gas agreeing the renewal but the proof will be when the old tariff ends at the end of this month.
To be honest I have low expectations...
