I emailed them about my displeasure with their new system and this was his reply:
Sorry for the delay in getting back to you. We can not go back to the old way because of the overload to the system. Last year in one hour I had over 1000 e-mails complaining about the crash in the system. We spent the first half of the year trying to find a new appointment system that would work with our process and unfortunately it is not out there. I did not trust the service we are using to open up at midnight and hope that it works.
