Scam???

hi I received an email saying I had signed up to a music membership monthly to be charged £40 at the end of the month, when I haven't done any such thing. there was a link in the email to cancel and manage subscriptions but the link doesn't seem to work? I'm not sure if it's a scam or not as the email seems to be from Apple, it knows my Apple ID? Any help/advice appreciated as I don't intend to be charged for something I havent subscribed to or bought, thanks!
