Findandloc's Unauthorized Charge and Subscription - Need Immediate Refund

This is the first time I’ve heard of a program called Findandloc, and today money was withdrawn from my account — I don’t understand why. I didn’t sign up for any subscription in the Play Store and there are no subscriptions listed, yet the funds were taken. How can I get my money back, and how do I cancel this subscription if the service activated it on its own? Where can I check these charges or whom should I contact to request a refund?
