Zero stars!! We have been with British Gas for 25 years and never had a problem until now. The new IT software that has been fitted last year is not fit for purpose, maybe it is the same software that the Post Office had installed. The old system was easy, you went on to the app and put your gas/electric meter readings in, the bill came back and taken out of my account after 10 days. Now i get an estimated hiked bill, i put the correct readings in to the app and they still take out the estimated abount. Last time i went on the phone i was on an hour, passed round to 5 different people, could not understand me (or them) and hung up on me. The customer service is terrible and there is no service, 1 woman told me to listen, i told her to listen as we are the customers! So yet again an estimated amount has been taken out of my account of 3 times more than it should be. Had enough of this company so will be changing to another service provider. Do not go with BG at any costs!!
