Need different EPCS vendor

I recommend that Evident terminate their contract with DrFirst. Their support is worthless, they have been utterly unprofessional/rude, and simply close tickets they do not wish to address. I have a surgeon that was previously using EPCS w/o issue until he got a new phone about 5 months ago. No matter what we do, we cannot get him re-authorized, we completed all of the recommendations put forth by DrFirst to no avail. (we do this all the time for other providers, never an issue until now). Unfortunately, the poor performance of DrFirst is a reflection on Evident in the eyes of our providers.
