I used Bulb as an enregy provide for the past two years. I was recently offered a free smart meter instalation. My smar meter was installed on 30 May and it has never worked since then. Bulb customer service team is confident that my smart meter is working but it is not sending any meter readings. So neither Bulb nor I know how much enregy I am actually using and I am currently paying a very high fee estimate. In short, I have called about 4 times and made an official complaint. However, I keep getting generic emails and responses with no time estimate or any actual help. I still have not been told whether my smart meter can be fixed or when this will be done. So in summary their customer service team is terrible. If something goes wrong please do not excpect any help for them. I have already made a complaint to an energy ombudsman and hopefully they will deal with this from now on.
