You can add NPower too,
It took us months to get over paid bills back and then we had to get "watchsomething" to get them to kick ass. It wasn't a small amount either.
In 18mths they never read either meter once or took any notice of our sent in estimates. The overpayments just kept climbing and climbing.
During that time we had a new gas meter fitted due to a fault, it leaked. So the reading was now 00000, they accused us of fiddling and didn't know how to bill us so they guessed the old meter reading.
Priceless I tell ya....
