Do not Trust British Gas, I am flabbergasted by the fact British Gas have come up with an old bill from 2016 that I assumed was settled,when we transferred to Sainsbury's, no correspondence or reminders, just a text from a foreign call center 3 years later threatening late payment charges & reporting me to debt collection agencies,even though we are still with them via Sainsbury's, so what took them 3 years, just outrageous and to make matters worse they have reported me to credit agencies so it goes against my credit rating. And to add insult to injury their engineers failed to turn up on two occasions to fit a new meter, and all they do is say sorry and offer £30.00 odd pounds off a 3 year old bill I did not know still existed completely unacceptable.
