I've been customer for more thn 7 years! And since I've asked them to update postcode on National Data Base, which has been done by npower a few months ago, all went south! Customer service gave me different info every time we rang! I've spent more than 3 hours on the phone!!!!! At the end I've left them and I'll NEVER be theirs customer again! So dissapointed!!!!! Please consider carefully to became their customer even if you're in the position to accept high energy prices!!!!!
