Poor Customer Service

I’ve recently signed up with Bulb, and I am struggling to get answers from then by email or facebook messanger. I had a Scottish Power 2 rate smart meter. Bulb think it is a single rate meter. I can therefore only enter one reading, not two. So far I have emailed photographs and copies of old bills, and I am getting nowhere. How can I resolve this? Cheers, Aidan

Maybe better to try phoning or live chat.
