Jin,
I apologize for your frustrations with Fast-Track Support, however, please note that the $5 fee is only an introductory fee for the first 30 days. The fee for "Fast-Tracking" your support request will potentially be higher after 30 days as noted in our blog here.
Additionally, we've been expanding our support team and have 24/7/365 on-site coverage to allow for this kind of option to be available. In fact, most support requests are getting responded and resolved quicker than it ever has in the past. The Fast-Track Support is merely offering an emergency option for people who want to expedite their support requests, and only available during specific timeframes M-F where we have the most staff available online.
If you ever have an issue with the level or quickness of service you have received, feel free to reach out to myself via the forums here or by asking for a manager via the ticket. We are more than happy to address service-level issues.
Thanks!
