This is an excerpt from Pattaya City Expats latest info, look and learn, but i doubt it.
"Although this system has been available for use for some time, we have not previously announced it because of several reports that when the person making the appointment arrived, they were told to get in line to get a queue number. Thus, to use it to make an appointment offered no benefit.
However, we now have 3 very recent reports regarding this service with 2 having positive results (retirees) and 1 having negative results (extension for Visa Exempt entry)"
