Budworx can take a good few days to respond to messages, I can only guess at the volume they get but it must be huge. They have posted in the forums stating they will consider refunds even for finalized orders, they claim to consider each issue on a case by case basis so if you have good buyer stats and/or an established relationship with them it should help you work out a resolution. If you have given them a negative review and low feedback score before having some discussion with them I'm pretty sure you will burn any chances of working something out. I understand they have been slow to respond but if it has literally just been a couple of days I would invite you to change your feedback and give it a few more days and if nothing changes then you edit your feedback accordingly.
