Support normally can be a few days (depends on the number of requests opened).
That does not sound like an envato email more like PayPal or similar.
Normally envato send you an email saying “Thanks for buying with us. Below is a summary of your recent purchase. You can download your purchased item at your downloads page and view your invoice(s) on your statement here.”
Your profile does not have a buyer badge which usually means it did not process. Had you just opened your account before buying the file? If so did you confirm your email and account before buying?
Hopefully support will be quick and can fix it
