Hello,

I don't have power to check user account for that. You can raise a support ticket using the link below. Pick the "Product not receive button and fill up the form in there. Include all your purchase information and your issue in there and Support will help you from there. Remember to record down the ticket number for future reference if needed. Do not raise multiple ticket since that will only confuse the system. Send once and wait. Ticket will be answer on first come first serve bases.
