I joined Bulb about 2 years ago, all was ok until I changed to a smart meter, only time my account has been updated in 9 months is from a submitted reading. You ask questions why and just get fobbed off. Unless I get updated Bill’s in the next month sad to say I will be leaving.
Just submit manual monthly readings via your Bulb account until it’s sorted. That’ll bring your account up to date and be no different to before. You’re one of thousands in the same boat and communication over smart meter issues has been dreadful. I wouldn’t guarantee changing supplier will solve your problems.
Even when I submit it ends up a mess, losing confidence. Simple answer is keep customers upto date regarding any issues and people will give them a chance.
