we had a fault with our gas smart meter 15 months ago rang every month and complained and had a million promises to send someone out after being charged £666.52 every month on a estimated bill paid everyone up until 3 months ago due to being overcharged (should be around £96 a month) NOW after another call they want to take legal action ............ well my story is why pay £550 a month more for something we are not getting (GAS) absolutely useless , helpful on the phone but no call back, no appointments , so promised engineer AND today we get told they do not own the smart meters .......... good old UW , see you soon on martin Lewis
