Just as an FYI, most of the time when you make a payment via paypal and the store you buy from (any store, not just Rendo) doesn't get marked as paid it's generally an issue on Paypal's side not sending the verification back to the site. That can happen if they are running maintenance, tweaking something or even if they have a large volume of users bogging down the system. That's why there are often a group of people with the issue at the same time.

When you raised an issue with Paypal over the payment not being marked paid, they automatically put a hold on the payments and create a dispute ticket. Your screenshot shows that a dispute ticket was opened, that's why the funds were put on hold.

Sometimes it can be the store, if they are upgrading store software or running maintenance but it seems far more rare.

Generally just contact the store in question, because if you contact Paypal they will hold the funds as a dispute.
