Yesterday morning I tried to contact npower at 9:30am with regards to my Gas Pre-Payment meter displaying the error message CALL HELP.. when I finally got through to them at around 11:30am they told me an engineer would be out within 4 hours.. 5pm an engineer did finally arrive and told me their was a fault on the meter and it needed to be replaced... to which I had to phone Npower once again. explaining to them what the engineer had told me to tell them.. They instructed me that another engineer would be out within 4 hours to replace the meter... He never showed up... I told the person on the phone that I hadn't had any gas since Friday night as it was impossible to get intouch with them without being cut off or what I think was the phone being put down their end.... Also whilst on the Npower website I noticed I was nearly £500 in debt with gas. this is from a bill 31/05/2013 Your bill (PDF) £489.47 CR 03/07/2013 Your bill (PDF) £258.68 DR as you can see ive used over £700 In a month on gas which you can plainly see from the months it was summer
