Started off great with fixed rate and then after one missed payments I was taken off fixed rate and promised a second higher fixed rate ...within a couple months later I was told I was not on a fixed rate and they complained i was using more tthan I was paying and increased my payments once again (£270) and then once again to nearly £350 per month yet I was hardly home to use that amount per month, after all im not running a Restaurant......Scottish Power Meter Readings are a scam , they don't investigate properly, not helpful and someone must have been pocketing my cash I'm sure ..so glad to see the back of them !! Stay Clear ..you'll have sleepless nights.
