Refund Money

I have my linkedin account for the last many years and from last couple of years they want to give me Premium account. But I don't need it so I never applied for it. I was charged for linkedin premium features which I never used it. While I subscribed for premium feature a month ago.

After some time they offered me Free premium account and for that I selected the option.

I am shocked after when they deducted $59.99 from my given card details. 

I need my money refund asap.
