refund for renewal charge

I had a monthly renewal charge occur on my adobe acrobat subscription one day prior to the automatic renewal date.  The renewal date was supposed to be on the 12th and the renewal charge occurred on my credit card at approximately 6:00 pm on the 11th, which was just 30 minutes prior to me going onto my phone to cancel the renewal. I am requesting a refund because this transaction was not a fair process as it contradicts the official date of the renewal date and I was not even given the chance I should have been permitted to cancel it one day prior to the official renewal date. I should be given a refund as I have had this subscription for 2 months and no longer needed it.  Please help with the refund. I can provide a renewal transaction receipt that was emailed to me on the 11th showing a charge of $9.99 at 6:01pm on the 11th (one day prior to the official subscription renewal date).
