Absolutely terrible. Declined offer on smart meter on the phone and in person yet they still fitted it.Also taking advantage of a disabled person by trying to charge me over £4000 for aprox 3 months electric (single man. 1 bed flat) later to say it was an error and that they are switching me to prepayment due to an ERROR MADE BY AND ADMITTED BY THEM. Prepayment have service charges so I guess its an apology to UP MY RATES? AND LEAVE A MAN MEDICALLY DEPENDANT ON ELECTRONIC LIFESAVING EQUIPMENT IN HIS HOME AND IM DISABLED. IT SEEMS LIKE THE £4000 THING WAS AN ATTEMPT AT FRAUD TO ME?? As it was only after challenging them several times did they say it was a "mistake" Luckily I have a few reps willing to help me and a very large.. let's say online influencer ready to support me out of the goodness of his heart ❤
