It’s a worse company and scammer I been with them from 5 months and I been paying monthly DD. When I ask them I want to go for top up because I’m not using anything they sent me bill of £1770 and when I call them they said your meter is not right. I explained them that I don’t cook at home not using heater and it’s a flat how is possible but still they didn’t sort it out my issue. Please don’t join the British Gas they are so doggy. I’m still waiting for to change my meter it’s been 2 weeks I call them everyday and explain them same thing again n again but no progress.
