Support Email not reachable

Hello dear support team, I find it very interesting. That you do not respond to my requests. Let alone answer the question in the forum. Your support email or whatever email is not found by my mail system. Then how should you write with them? I have been making a request for over a week and I am skilfully ignored. The new update does not work. The site in general has bugs. That worked for the demo. Demo import does not work. I ASK FOR IMMEDIATE HELP
