If you want to be financially challenged on a monthly basis join Bulb. They estimated my usage to cost £770 for January after giving them further readings the bill was calculated at £330. I instructed them not to take £770 and they told me the lowest direct debit they would accept was £390. So they took this then 2 days later withdrew £260. I tried to call them with no joy as there customer service is garbage. I am now going to instruct my bank that the 2nd withdrawal is a fraudulent transaction and that Bulb have stolen £260 illegally from my account. Thought I was doing my bit towards saving the planet but looks like I am just lining the pockets of the corporate elite. No wonder this company has gone to the wall their customer service is shocking. Wish I had never switched to this company.
