Hi Jerry
You have paid £15 to the old owner of the site, who i'm sure should be noticing these payments coming in and reversing them automatically - but i'm no expert on paypal standing orders so i shall not comment. This is happening quite regularly unfortunately, but in what appears to be the majority of cases you should recieve a refund from him if you ask.
Try emailing him through paypal, or claiming the money back through it's own procedure. Sorry that this has happened to you - you are not alone. If you need any further assistance, please PM either myself or one of the moderating team.
Kind regards
Lee
