I'm sorry that you're having issues with Stocks.Exchange. The team at SE does not always give us a prompt, or even clear reply regarding what's going on. This is objectively a problem, there's no doubt.

I appreciate the advice regarding potential new exchange leads and I can assure you that I've personally thoroughly reviewed all three you listed. We do have a listing on SouthXchange (https://www.southxchange.com/Market/List) coming shortly and while I can't discuss details regarding our discussions with exchanges, I can tell you with 100% certainty that future exchange listings are not going to be an issue.
