No support, no response, unethical business

I tried to give this plugin a fair shot and sent multiple tickets to support. No response. If you try to configure your document, child menus end up flipped upside-down. The PDF function doesn’t work, either. I’ve been trying to contact Sanjeev Mishra and his “marketing firm” Staenz for a refund and have received no reply. Please don’t bother with this plugin/developer.
