Unexpected CVwizard Charge

I am writing to request a refund for an unintended payment made to CVwizard for my subscription. I believe I was on the basic plan and did not intend to continue with a paid subscription, as I am still in the process of seeking employment and my financial situation is very limited. I was unaware that the subscription would automatically renew and result in a new charge. The most recent payment of 19.99 was taken from my account yesterday. After noticing this charge, I immediately cancelled my subscription. My CVwizard account is registered with the email address dmorris-el***@stu.ucc.edu.jm. I kindly request a full refund of this most recent payment, as this money is all I have to send my children to school when school reopens on Monday, September 7th. I would also appreciate written confirmation that my subscription has been cancelled and that no further payments will be taken from my account. Thank you for your understanding and assistance, and I look forward to your response.
