Testora IQ Charged Me After Cancellation – Stop Payment

I cancelled my Testora IQ subscription about a week ago, yet I was charged again today 07/19 for 39.98 USD, as shown on my recent Bank of America transaction screen. Being charged after cancellation is unacceptable and has caused me both financial and emotional frustration. After noticing the new charge, I contacted you by email, but despite this, the issue has not been resolved and the payment is still pending. I do not understand why I am being charged for a service I already cancelled. I request that the current pending payment to Testora IQ be immediately stopped and prevented from being finalized, and that no further charges be made to my account without my explicit consent. I also ask for written confirmation that my cancellation has been fully processed and that my subscription will not be renewed again.
