I had a door to door sales man from shell, after looking at my smart meter said I could save £20 a month, as i was currently paying £85, i agreed n signed up only to find out after a friend said it was impossible looking at my units or what ever they are, rang to complain n they agreed it should of been £85 a month, am now going through ombudsman n just received my first month bill £120 !! What a scam of a company with no morals, they should be a shamed of themselves!! And i totally agree with the previous ladies comments about the trust pilot reviews, staff clearly writing those !!!
