Hi

How do i go about changing from Ultra Fast with home phone - Cable 80GB data to the Ultra Fast Naked Broadband - Cable 80GB data. After a year i have found i really don't use the home phone line enough to justify the price differential. I only got the phone line in the first place because it was the same price as the naked plan at the time. I believe i will have come to the end of my 12 month contract shortly, would there be any charge for this change anyway? 

I cannot see an option to change this plan through the customer zone or the vodafone website.

Thanks
