I would like to give a no star rating but that option is not available here. I had gas and electricity supply with British Gas. Had lots of issues with gas meter reading as there system somehow reverse the readings at times and I used to get a number of phone calls asking to pay extra £1000 in addition to the monthly direct debit of £52 for a two bedroom flat. Hence changed the service provider in October 2017 and I was told I’m due for a refund of £750. In December I got a cheque from British Gas for £1280. Two weeks later I got another letter from them saying I need to pay £1337 to close my account. I have disputed the bill. Their call handlers and complaints team repeatedly said I need to pay £1337 to close the account. It took nearly two months for them to finally accept that I was due for a refund and I need to pay only £870 back after clearing the cheque they send me. Meanwhile I was getting repeated calls and emails from their debt recovery service saying I need to pay £1350. Stay away from British Gas if possible. Worst service ever experienced.
