On a 2 year plan ending in Nov 2021. Mother, who I lived with was lumbered with them by energy helpline and ofgem. Supposed to be cheaper than previous supplier but when introduction paperwork arrived it was dearer. Mum dealt with bills by direct debit. Anyway June 2020 mum died of heart attack I informed together energy and asked to be sent direct debit form, have smart meter fitted and as I'm on minimum wage put me on cheapest tariff. Today one year 2 months on I am still waiting for all 3. Meter is in garage so I sent in meter readings. 7 months ago get letter that readings are on computer bill on its way. I have been writing complaints about my 3 requests to customer complaints, ceo, accounts dept and always the same man replied. Time passes no bill, then I get home on anniversary of mums death to find a massive estimated bill. Money is taken from account, I complain, send meter readings get a new person replying, and what happens, yesterday I get another huge estimated bill. My meter readings are on the left their estimated ones which for some reason they used on the right. Money taken out of account I expect and no refund, no apology I've given up on smart meter as its too late. Have sent in another complaint asking for my money back and a leaving date. My treatment has been awful. And the bill arriving on mum's death anniversary was deliberate and spiteful.
