Unwanted subscription renewal

I have received a subscription renewal reminder for April 2020 and advice that my credit card will automatically be debited on the "renewal date". But I paid for a 3-year subscription on 18 February 2019 with a renewal date in 2022..  There should not be any renewal in 2020.  How can I stop my credit card being debited for a renewal I was unaware of and do not need?
