Good afternoon. I have no problem with the application, but I have questions with the payment of the subscription for the next year. When I wanted to stop the subscription due to the high price of 79 dollars. You gave me a new price at 39 $Can., What I agreed to. And now I see that you have removed 68 dollars from me. I demand a refund of the money withdrawn in excess of the due amount, otherwise I will refuse the subscription at all.
