Is that a joke? They were the worst energy company i had ever been with. I moved from British Gas to them a few years ago and was locked into their fixed price deal until October last year. For the first 18 months and despite constant pestering from me, they didn't bill me for my Gas usage. I was providing them with monthly Elec and gas readings yet they never billed me for gas, just the elctricity. Every time i phoned up and after being on hold for over 30mins they either cut me off or transferred me to another department who then cut me off. They never answered emails and they have by far the worst customer service i have ever encountered. Eventually the only way i got it sorted was by sending recorded delivery letters to everyone at head office i could find a name for. They finally provided me with a "case officer" to sort things out (who i still couldn't get through to on the telephone despite having a "direct dial" number) yet it still took over four months to sort things out. Luckily my direct debits were enough to cover the whopping bill for the gas. For all my troubles they gave me a credit of £20!! Absolute joke of a company and as soon as my contract was up i swapped to M&S Energy who have been great so far.
Swings and roundabouts, I've been using them for 6 years with no issue. Far better than my Npower and E-On experiences.
