Yes, it is often the VA in Oakland calling to remind you of an upcoming appt. The call usually come one or two days before your appt date. Sometimes a message will be left with the appt information. The call is automated.
Often it is an automated system that doesn't always work properly when it gets a voicemail. Thus no message and you don;t know who from the hospital was calling.
received call yesterday from automated machine asking what month/year received flu shot from VA. Glad we are spending the billions on government computers. No money for VA education.
