I'd like to know why it is considered acceptable that this office employs receptionists that turn the ringers on the company phone down to a dull hum or off completely during business hours.

I haven't had that experience. I have always found the staff to be attentive and professional

Go to Paton vet! They are way better! And way more professional!

Anytime I've been there I've heard the phone ring.

if it helps, any time I have left a message - they have followed up with me within 2 hours.
