I just purchased Avast Internet Security, but I put incorrect Email, so that I can not retrieve my purchasing details.
also, When I activating the product, the application start freezing and I restarted the application but nothing upgraded!!
Obviously you wont be able to able to give an Order ID (on less you wrote it down or took a screenshot) but complete as much as you can and use the text fields to give as much additional information to try and help find a record of it.
Since the Order ID is a required field, it may complain, if it doesn’t let you submit without something, you could try email/order ID not received.
