Non existent, terrible customer service, British Gas are money grabbers who never ever want to refund your money, even when you are entitled to a refund. They never do what their agents will tell you will be done over the phone. When you ring them again for the 100th time, you'll have to explain yourself from square 1, because their customer service reps haven't taken proper notes of your problem/query. Their customer service reps are incompetent and unable to complete very basic tasks. Worse some of their reps just want to argue with customers instead of sorting the problem out, and they will just pass you onto another department where you will be put on hold once again, and once again will have to start all over explaining your issue. This is a very unprofessional company that are dishonest and greedy and they hoard people's money. They need to be reported and investigated.
