Charged $130

Hi,  so I usually don't check my credit card bill till the end of the month to see what I need to pay. Was confused to see that $130 has been charged for a year plan,  since I never signed up to renew it again. I had no emails about them renewing my plan and went on to see that the plan i cancelled months ago isn't cancelled. I would like my money back I feel cheated, since I can't afford $130 for a plan that I thought was cancelled and that I never use.  Now i have it for another year for no reason.  Please give me my money back.
