I’m sorry about the confusion. I can confirm that you did indeed purchase Vercel Pro, rather than v0 Premium. We’ve passed on this feedback internally to make sure we don’t have future confusion.
For now, I recommend that you create a support case for a refund on Vercel Pro. Feel free to attach the link to this case for reference.
When you’re ready, you can purchase v0 Premium by going to https://v0.dev/ and from the bottom left-hand corner, click your name then Upgrade Plan.
From the modal, click Premium and follow the steps to upgrade.
I apologise again for the confusion, I hope we can get this resolved for you as soon as we can!
Note: I removed the image of your invoice in your original post as it shared some sensitive information.
