Even though at the pricing/invoice, it looks like Envato is charging for the “support”, the item support comes with the main item for free for the first 6 months.. That’s why you’re not “officially” purchased the item as well as your license has been provoked, if you’re still using it on your website, be aware of it’s unlicensed and you will have to remove the item…
If it’s about “extended support”, it’s something wrong with Envato system. Contact support.
