STAY WELL CLEAR!
I thought how bad could it be, just buying one pianos score for 99p. I was wrong! They signed me up for a subscription (after free 7 day trial) WITHOUT MY KNOWLEDGE OR CONSENT! I only realised from the email saying I was signed up to a subscription. Now I'm struggling to cancel. VERY VERY BAD EXPERIENCE! Edit: Shame on you, replying as though you've done nothing wrong when you know exactly how you're trying to scam people. I've reported you to the National Cyber Security Centre and I hope they shut you down.
