CollabPay: Multi Vendor Payout

We installed this a couple months ago, went through the setup process and confirmed everything was set up correctly. We ran our first collab with a another business we are very close to and it was a disaster. Payouts stalled and just appear pending, linked products are randomly being skipped in the reporting. I've emailed numerous times for help and just keep getting "we have passed this on to our developers" The last 3-4 times I have emailed I have just gotten no response. I really want this to work because if it works as described could be a great tool for us. However, support is terrible and functionality just isn't there. Edit: We are still working on getting this functioning correctly, but they have now been responsive and seemed to have figured out the functionality issue. We are going to continue testing.
