PM Pediatric Care review: MD professionalism

A am a health care provider that responded to a PM pediatrics is Massachusetts, I had a significant issue with the professionalism with one the physicians at the location I was at. I reached out to PM pediatrics to voice my concerns. I was given an E-Mail address to contact. After sending the Email it was returned stating the address was not valid. I contacted PM pediatrics again requesting another venue to voice my concerns. The gave me a phone number that has no option to do such a thing. When I contacted them again, they gave me the same E-Mail, when I explained that the E-Mail was not working the advised those were my only options. I suppose they are not very concerned with the caliber of people working for them.
