Moving house

I recently moved house, having been with Bulb fo 18 months and having no problems, I didn’t hesitate to take them with me. My old homes account was in credit by a little bit, I was informed it would be credited by 5th September, and my new home account was efficiently set up and to be charged from 12th September. No problems! Unfortunately, although the charging aspect of the service was very efficient, I am still waiting for the refund, some 3 weeks later, after 3 emails. I find the lack of contact number, or efficient contact center very frustrating in this situation, does anyone else have this experience? How did you resolve?

Your final reading will have to be verified by a 3rd party which can take up to 6 weeks.
