I accidentally purchased LinkedIn Premium. My mistake. Thirty days later I was charged $69.99 via the Apple ID on my iPhone. Because I did not receive a receipt for 5 days, I called my credit card company to cancel my card. They could have just cancelled my Premium subscription or sent an alert. Instead they back doored this purchase through my iPhone. Lesson learnt. I have removed my credit card from the "purchase and subscriptions" settings in my iPhone and cancelled this subscription ($70 per month are you kidding me?).
