British Gas harrasment and extortion

[Guest]

British Gas are forcing me to pay for a bill that is not mine and not in my name. They stopped me going to the ombudsman by saying the case had already been through the ombudsman. It has not because I only just took over responsibility for the Bill's and any old ones are not mine. The got a warrant illegally without telling me when it where to get my representative. The will not provide any evidence or bills or the warrant number. I got an injunction but they got it overturned as the case was not ready for hearing on return. I'm not in the UK and they are trying to force me to pay 15,000 to cover their cost up front if I want a court hearing and if not they are putting in a meter to make me pay bills of over 10,000 which are not only estimated. What can be done to stop them bullying andcharrasing me? I have a tenant and a air bnb guest room and I cant manage this meters from where I live abroad but I will be bankrupt if I cant make some money.*
