Q: fake invoices for music membership

I have received an invoice for a monthly music membership for 45.99 pounds. I thought it was just a mistake so clicked the link that says Cancel and manage Subscriptions. It tried to take me to a Youtube link. I stopped it on my iphone , came onto my Apple Account, changed my passwords and security questions and have also sent to Hotmail as a Phishing scam. On the email address it came from...Apple TM Support Center, it also lists a Personal email..aiu923mun1@alumni.txstate.edu  . I am also going to change my hotmail account password in case...Be careful of this scam.
