Changed to npower recently ever since all ive had to do is to ring to coninuously sort the issues. Recently november 14 gave up to date readings to find they owed me over 500 as i had over paid. Even though im in so much credit they seem to change my dd payments higher after sorting that i requsted some refund not the whole amount. And since november still no refund. After ringing again today 20/01/15 they have no answer why i havent got it wouldnt lodge a complaint.. i mean why cant they just do as they say... instead every phone call i am back to square one and now i have to start a process again get new reading and call back... i know its not a big thing but when you are diasbled and use aids its not easy reaching the meter to read it.. and having to wait till someone can come and do it for me.. and ill most likely have to wait again to get told it will be another month before i get this refund... ive never come across a service so slack and unfair and upsetting... apaulling customer service and i have decided to report and find another provider.. im 67 and never had a problem with other providers and now im in the worst days with health i have issues again and again with npower.. i would not reccommend to anyone and cannot wait to move
