Who called from 9494152151

I received a call from this # sounding like confirming an appointment with Dr Robert Chen, which I have now idea.

It's a Dr.'s office service confirming an appointment with your Dr. That's all. Relax.

This is legit.... it's just an automated call used by some doctors. I made my appt through ZocDoc to set my appt with my Doctor.

The appointment reminder voice mail starts too soon and cuts out the important information as to it is from.
We will ask our Dr. office, etc. if they have chartered this worthless endeavor.

Yes, this is an appointment reminder -- extremely "automatic" the information --- names (provider and patient) and date and time are inserted.  They are very unclear and in the case for me today, with the wrong first name of the provider.
