subscription to Spotify

I got an email confirmation from Apple/Spotify for a premium bill $45. which I did not order. It is signed "The App Store team" .

The link 'to learn more or cancel' won't open ("cannot locate internet server or proxy server" )

I have checked my itunes account, both current one and a very old one that I haven't used since 2013 , and there is nothing indicating an order for Spotify. I also checked credit card accounts, nothing noted.

What now?
