Hi all,
Thank you for the responses so far.
I do have bills/screenshots/proof of my credit balance at the time which should be sufficient evidence to show my switch should not have been blocked.
I am no longer in the property but took meter readings when I left.
I wasn't able to switch after being made aware of still being on Npower as by that stage a balance had accrued (the disputed balance), which would have made it impossible to move to an alternative supplier given it was over £500 by then.
I did speak to a customer services representative about the issue.
To be fair the gentleman was pleasant, he said Npower would make a goodwill offer to reduce the balance by some £80 or so, far less than what I was out of pocket.
I rejected the offer and asked him to raise the issue with the ombudsman stating that there seemed no point in both parties waiting for the 8 week or so response allowance to try and rectify the matter when we had both come to an impasse.
Since then I have heard NOTHING from Npower, no calls, no emails, nothing.
I have written letters to them, ignoring Wescot completely, to no avail.
I want to raise it with the Ombudsman, which I will do now.
Hearing that Wescot are not a debt collection firm has made me feel much more comfortable so thank you for that.
It's an absolute shambles and I can't believe Npower take such a hard line given such an obvious error on their part.
Really appreciate the help. If anyone has any other suggestions please let me know.
Harold.
