BorgCymru I've PMed you, but for other folks...
... here's HOW
go to your own page and click on 'account', it's underneath the 'sign off' button at the top.
Your account page tells you how to cancel your subscription. If that doesn't work please contact Matt via the contact page and not on the forum, he may miss it if you post it in here.
Cheers
BorgCymru I hope it's only a temporary leaving, unless you've met someone then I hope it's permanent.
Good Luck
