Dead air, caller ID said "Patient Referrals" but nobody was there when I answered. We are a dental office so I assumed they wanted to sell us something that "gave us more referrals."
Calls at least once daily (twice already today). No one responds IF I happen to answer the call. No one leaves a voice mail message. This is an academic institution & I don't have time for telemarketers, surveys, or just plain nonsense calls.
