To get a full refund of a subscription of a plan that I had already cancelled months ago

Dear Adobe Support Team,

I am writing to request the cancellation and refund of my Adobe subscription. I never used the service and did not receive any email notifications regarding the trial period or its expiration. I only became aware of the charge when I received my credit card bill transaction.

Please I do not have enough money to pay my house rent because you somehow miraculously charged me RM134.37 for a subscription plan that I never used and already cancelled months ago. 
 

Please process the cancellation and refund at your earliest convenience. Thank you.
