I have been a customer of British gas on the electric key meter side I have complained for years about how high our bills were and that we were being overcharged I have since found out after trying to leave them that my bill is double that to which a 2 bedroom property should be I gained a debt which we had been paying off and I asked for a settlement figure they then received my payment in full I explained that I was joining another company and not only did they not remove the debt but also blocked my move because of the debt I paid I have made more than 9 calls to British gas regarding this whole issue were I have been lied to and not received phone calls back when promised one.to make things worse they told me to top up with them again and when I put the key in the meter it would clear the debt I have tried this now at 2 different shops and spent 25 mins in the last trying to achieve this however to no avail in my experience the customer service is non existence and everything thing I told the people who answer in a far off land I had clearly just wasted my breath if you read this please take note so you don't encounter the problems I have had myself
