I got into nearly a £1000 in credit with Scottish Power and it resulted in them sending me a cheque for £700.
They're explanation was my online tariff wasn't correctly set up so the £95 pcm for duel fuel online tariff wasn't correct. They then dropped my monthly direct debit down to £60 so I was pretty happy.
Im on a deal that I need to enter my own readings so I was a couple of days late putting them in so they email an estimated bill and guess what my monthly direct debit shoots back up to £95 pcm.
I live in a 1 bedroom flat with fairly new energy efficient gas central heating system so £95 pcm is ridiculous. I signed into a fixed pricing tariff a few years ago which expires in 2011 as Martin ¨MoneySavingExpert¨ Lewis advised it. due to higher energy prices.
