WHAT GIVES? Money taken from my PayPal account but shopping cart still full??? NO EMAIL ADDRESS

Something went wrong at your end just now when I was completing the order for Woocommerce Product Slider. The Cart froze but then I received a confirmation email from PayPal saying the payment had gone through. Still no email from you, no download link, no way to contact you except through this public forum. Whatever happened to having an email address for your customers? Not good enough. Either send me the slider or refund my payment.
