Need help with plugin fundraiser

I really need support on a plugin that I'm using. I have been going back and forth with support via this portal but it takes days to get a reply and then it doesn't solve the issue and I need to wait a few more days again. It is not really reasonable to take a week or two turnaround time between just a couple of sentences for a small issue. Is there any way to get a phone call or chat, or at least a reply quicker? I purchased this plugin and we need to launch our site with it on Thursday so need to figure this out ASAP.
My number is (removed by moderator for privacy). Thank you for your assistance.
