If you haven't placed the order yet and are still in the basket, simply click 'Remove' under the line item 'Boost 7 day free trial', then complete your purchase.
If you have already purchased go to My Account > Manage account > My membership & devices > NOW membership, scroll down until you find Boost and click 'Cancel Boost'. Make sure you then follow all the subsequent steps as it will ask you 'are you sure' a couple of times before you get to the option to actually cancel. Once you have done so you will receive an email confirming your cancellation.
