Long story short, I’m 10 months into a dispute with British Gas over billing. It’s a lot of back and forth but essentially I’ve been told 3 separate, conflicting facts by different team members which has landed me with a £400 debt they want me to pay. They are saying they never said something which they did, so I submitted a private access request via an external company with the view of taking them to ofcom as they are refusing to resolve. Today, after 3 months, I’ve received the recordings of all the times I called them (the debt is incorrect) but what I didn’t also expect to hear was a call handler speaking to a colleague whilst they had placed me on hold. He says to his colleague that he agrees with me that I haven’t used what they’re charging me for, but “what should I tell her, because she’s doing my head in”. He then comes onto the call with me and lies. What’s my best next step? Just straight to ofcom?
