Why Quest does not offer any support?

Everywhere i go on its site, its just PDF files. Even those videos dont cover MMED  or MMAD in details. In other words, it doesnt show STEP by STEP how to install MM. The PDFs only tell what needs to be done but not how to do them.

All phone lines dont answer. All emails dont answer. They say they offer help for trial people but how to get help?If they r so closed like this.
