Help me delete hosting site?

[#1]

Dear *******
I'm sorry to tell you that unfortunately for the past few months we have
been taking payment for your £1 per month domain, *****.co.uk.
Unfortunately this hasn't appeared on any of your invoices.
The problem has now been resolved and the domain charge will show on
subsequent invoices as a separate item.
What happens now?
-----------------
A separate invoice will be raised along with your usual subscription
invoice for the amount of £5 that has been billed over the past months.
I'm very sorry for any inconvenience caused to you.
HOW DO I CANCEL THE HOSTING OF THIS SITE? CANT FIND ANYTHING IN MEMBERS SECTION?

Go to:  http://www.nominet.org.uk/registrants/maintain/cancellations/ ; and follow the instructions.
Raise a ticket with PN and tell them you are/have cancelled your domain name.
Bee good

I think you will need to raise a ticket to request that hosting is cancelled.
