I have received a letter today from Npower.
"Your Payment scheme hasnt been set up correctly.
We've tried to call you to explain an issue with your account setup. Unfortunately, due to a system issue, we were unable to set up your payment scheme correctly, so you've only been paying for usage on one fuel."
I phoned the customer number, on hold for 30mins.
She has said I have not payed for gas from 01/01/2014 - 25/01/16. I'm afraid I wasn't brilliant on the phone and wasn't sure what to ask.
I am on a Price Protector December 2017 dual fuel setup which is paid via DD.
They are currently going to increase my DD by £54 over the next 16 months? My bill has effectively trebled as now ill be paying the correct dual bill and the increase.
Is there anything I can do? I'm assuming I have to pay for all the used gas?
