Prepay bill after moving house

I recently moved out of my flat (on the 11th of June) I have just received an email with an attachment telling me I owe £394.85. I had a prepay meter at my flat and was always in credit so I don’t understand how this could be possible? Can anyone shed any light on it? I called Bulb and they couldn’t tell me why I owe this money or if I do actually owe it!!!

You are posting to a Community forum seen by many, so I suggest you remove the statement showing your personal details. Best if you contact the Bulb team direct, their contact details are on the bottom of the Help page.

I appreciate you have already contacted them but they should be able to resolve your concerns, so press them again for an answer.
