Paid for plugin but no link given

I purchased a form builder this morning. Paid for it. Was told I would be sent a confirmation email but haven’t received it. They have taken my money but not provided the product. When I hover over my username and click “Downloads”, it just tells me that they have sent the email to my email address and offers me a link to resend. I have clicked the resend link multiple times, changed email addresses, checked spam, but nothing. Submitted a support ticket but the wait is 5 days and they have already taken my money! Please help!
