I had arranged to have a Gas Smart Meter and Smart monitors for both gas and electricity installed for 11 October 2021. I have been waiting weeks for the engineer. For some reason, British Gas decided to change my contact details and state a number which I have never had or know of. I have spent an inordinate amount of time today and took the time off work with the NHS to be at home. I eventually managed to get through and was told that the engineer could not be contacted by phone and the appointment would have to be changed if the engineer did not pick up. How dare British Gas to change my contact number without permission!!!! I am so frustrated with the service of British Gas and communication with British Gas - it is absolutely appalling!!! so much time has been wasted dealing with them!!! They do not even deserve any stars for their service.
