Npower have tested my patience.... And I'm losing! No bill for months on end, incorrect and duplicated bills then received. Opened a complaint/disputed and although they acknowledged that they had messed up (repeatedly), they couldn't put the situation right and put a default on my credit report! The staff are useless and often slag npower off themselves. I've switched supplier (e-on, who are much better), but npower are still threatening legal action on an account that is closed and satisfied (which they acknowledge). They are incompetent ameatures-don't put yourself through the experience! Even hearing their bulls**t adverts on the radio and tv agitates me now!
