The purchases you make from the application can be clearly seen on the page. In the same way, purchases made on the page can be viewed in your application.
To cancel a purchase you have a period of 48 hours before the date of use that you put on the product you purchased. Once these 48 hours have passed, it will not be possible to cancel.
