It has taken over 18 months to finally get the meters swapped back in the system so I am now registered to the right meter
During this time I was paying a direct debit set amount each month but the bills they were sending me were getting higher and higher, they knew these were wrong.
Now the meter swap issue has been resolved I've been sent a bill correction 5 pages long that is hugely complicated. They have not included back billing to 12 months, they have gone back to when I moved in 18 months ago and because I am in credit they said the back billing rules don't apply
Is this right? And what are my options?
