The story so far is.......I pay by monthly d/d and back in June I received a statement saying I was nearly £250 in credit, then a few days later, another letter saying they were increasing payments to £54 a month. I rang them for a rebate and to stop the increase and when I took another meter reading they discovered the meter number was different to the one on their system. I've been with them 22 months with no meter change and so far have had to give them a reading and confirm the serial number every call in the past 3 months!
Anyway, after twice being told it'll be sorted in 28 days, they have given me another 28 days, which will make 3 months from when I first called. Today they discovered that "it's Scottish Power meter change mistake and 'my' meter number is actually at the house 2 doors down from me.
They apologised but then 'advised' me to keep paying my d/d. I pointed out that I was almost certainly in credit and that if they were unable to prove what my usage actually is, why should I give them any more money. I also made the point that if it was the other way round and I owed them £250, they would probably starting proceedings to get their money.
Apart from cancelling my d/d any ideas on how to get things moving quicker? I was thinking about writing direct to the guy who was on Undercover Boss telling him how shit his service still is!
