British gas is the single worst, most incompetent and utterly non-sensical useless company I have ever dealt with. DO NOT EVER CONSIDER THEM. It has been over one month and they have failed to switch us from pre payment to credit despite us phoning them over 30 times. They have promised to call us back at least 5 times and failed to do so every time. They think it is acceptable to lie to you to get you off the phone. They then blocked our request to switch to a competent energy provider without telling us why. When we asked, we were told there was a £2 debt which we could clear for up to 5 working days. When I objected she promised to look into it and call me back. She never did. I then called the next day and the advisor said the debt was actually 77p and took my payment immediately. This company does not make any sense. They were also aware we had a baby but still cut off our heating and electricity without warning on several occasions.
