Got a reply

By letter saying: Basically its your job to check the price and request a change (Hmm I did mention it on 31st Jan on the phone ... does that not count?)

And by email: Dear Madam

Thank you for your email

I can confirm to you that your account is cancellation pending and will be fully cancelled on the 07/03/2008.

If you have any further queries please don’t hesitate to contact us.

This is a different response to the one I got yesterday from the person who replied originally to my email. Ah well.
Fingers crossed this'll be the end of it.

A cheque would be nice but I won't be holding my breath,

Moral. Check the price every week of your ISP service and complain the minute you're paying too much or the service is rubbish
