PDF Aid Charged for Monthly Subscription After Paid Trial

Today I noticed that PDF Aid charged me for a monthly subscription, even though I had only intended to use a paid trial and I do not wish to continue the subscription. The charge was made today to my account in the amount of 19.000 OMR, and my subscription is registered under the email address bijumonva***[email protected]. I did not plan to keep the subscription after the trial period and I was not aware that I would be billed this full amount. I am requesting that this monthly subscription be cancelled immediately and that the amount charged today be fully refunded to my original payment method. I ask you to review my case as soon as possible and confirm both the cancellation of the subscription and the refund of the fee.
