I moved into a property, I was told I was with british gas (prepared meters) . I have never worked with these before, so I requested for them to be changed to credit meters. After 10 failed calls and being cut off. I was told this wasn't an option. I had to wait 28 days from being in the property, then I was only able to change to credit meters after a smart meter was installed. So after 28 days, I booked in to get a smart meter installed, taking a day off work for this. The engineer comes, after 2 seconds he tells me a smart meter can't be installed in my propeety because of where my meters are, and that it is on the system for this house that a smart meter can't be installed. Totally wasted my time. I since left British gas after a month, now I receive an energy bill from them, even though I used prepared meters, for a month. Absolutely useless company. Don't even bother trying to ring customer services, you're on hold for hours and you get cut off and no one bothers to call you back. Not to mention you get letters EVERY SINGLE DAY sent to you. Worst experience of my life when dealing with an energy provider.
