Direct debit problems

Had bulb for around 3-4 months now, you have only taken 1 monthly direct debit, I am hoping I don’t get a huge bill… cannot update my gas reading on smart meter as it is different to what you got from my old gas meter. (Non smart).
I think I may be looking to leave soon

You should contact bulb directly via email, phone or live chat. See https://help.bulb.co.uk/hc/en-us/articles/115001240291-How-to-get-in-touch
