That's what this system is set up for. To protect YOU. Linkedin mislead you (allegedly) to believe there would be no recurring charge. They made it extremely difficult (currently impossible) to cancel these charges. Call your CC company and put a stop on all future charges. Your CC company will fight to help you. Remember CC companies make good money if you stick with them (a % of every sale goes to the CC company's pocket) so they want your business.
