Yeah I just cancelled mine because I can't trust bulb with access to my account.

Over the last year I paid what they asked as it went up and up and up every three months. Ended up with £1000+ credit which they had a variety of excuses for refusing to refund.

Stopped paying till it came down to £0, cancelled the direct debit and now just pay for my usage manually each month.

I'd rather pay by direct debit, but their system forces me to pay far more than my usage, so I'm left making manual payments each month.
