Do not use this company. I fought for 6 months to get them to lower my bills from between £500-£700/month while using smart readers saying my TOTAL mi they usage was between £70-£80. Finally they reimbursed me around £350 (which wasn’t enough) When I went to cancel my services with them at the end of the 12 months, they found “missed charges” on my account and said my refund was a mistake on their part and are trying to charge me another £800. I paid them £3,500 over a 1 year contract. Unbelievable. Please do not use this company. P.S. I have an email from them saying they made a mistake and that my opening reading wasn’t done correctly, and they send me the figure. The new charges are stating the figure they “discovered” was incorrect and it was actually a different number. I can’t make this bs up.
