Message Failure - no support

I have been using SLYNUMBER for my personal and business communications, and the service has effectively been unusable for over a month.In mid-October the app started logging me out automatically every day, which caused me to miss an emergency call even though my phone and Wi-Fi were working normally. A few days later, all of my messages disappeared and I stopped receiving any new ones.Since then I have repeatedly contacted support, followed every instruction (log out/in, uninstall/reinstall, check notifications, send diagnostic files and screenshots), and sent multiple “ESCALATE” emails as requested. I have attached the same diagnostic file several times and clearly explained that no messages appear in the app even when notifications arrive.Despite this, I keep getting generic replies asking me to explain the issue again, which makes it clear that my previous messages and attachments are not being properly reviewed. As of mid-November, I still have no access to my message history and still cannot reliably receive new messages.Losing a month of communications and having such poor follow-through from support is unacceptable for a service that is supposed to handle phone and text communication. Based on my experience, I cannot rely on SLYNUMBER for anything important.
