An Onerous Transfer

As I thought, NPower's solution to our problem is to pass us back to Eon, the very people we had run from in the first place due to their crass incompetence. The process will involve NPower refunding the money we have paid them since joining in January of last year. They call it an 'onerous transfer'. Eon will then take over as our electricity provider and we will pay them anything we owe from the money accrued from NPower.
At the centre of this fiasco is our electric meter which, according to NPower, is quite unique and cannot be supported. I find it therefore pretty much a given that Eon will have the same problem and we'll before long be back in the same position as we are now. I expect you're thinking why we haven't asked for the meter to be changed. Well we have and this would cost more than we are worth so this is why NPower would rather get rid of us and pay back what we've paid them. How ridiculous this whole saga has been.
We now await a letter from NPower explaining everything and the prospect of having to go back to the supplier we had originally fallen out with.
