Agreed it's absolute BS. I called them again and just got a half-assed email from a staff member. Sadly she is the only Avian vet in my area but if I drive 2 hours there seems to be good vets so next time I need to go I will go there.Call again and tell the staff you need to speak directly to the vet today.
If you aren't satisfied with the result, then its time to look for a different vet.
Being totally unable to reach the vet herself is completely unacceptable.
