Roanoke Clinic

I was a patient of this clinic, had a great doctor but he left for another place, gave me a name of doctor to contact at the clinic when needed. I've tried numerous times to make an appointment with no results, can't talked to anyone when I call have to leave a message but no one every returns calls. I don't understand this situation when I've been waiting to see the doctor always is there office personnel setting and talking letting the phones ring
