British Gas has billed my account for Glasgow address that is not mine

Reader from London worries ‘cuckoo’ will potentially trash credit score and hitch a ride when switching supplier

Around a year ago I noticed that my account on the British Gas app had acquired a new address in Glasgow. I have only one house and it is in London.

I called up its customer service number and I was told someone would look into it. I waited patiently but nothing happened, so I tried contacting the company via various emails I found online but still received no reply.
