I have paid for Yacapaca but all I see when I log in is free stuff
Any payments against Yacapaca resources would have been made before the pricing structure changed on 1st September 2006. See Is Yacapaca free? for current structure.
If you have paid, you may either convert your payment into a technical support package or you may have a refund. Please email email@example.com with your request, order details and invoice number
