I got a call on my cell from this number. The lady left a voicemail asking me to call back the Customer Service Dept at the Medical Center of Mckinney in regards to my daughter's boyfriend. He had been in job corps, got hurt & they took him there to be seen. For some reason they are calling me trying to bill me when I have never signed anything stating I was responsible or his legal guardian. He had me on his list to call & to come home to for weekend visits as well the person who stated to be his legal guardian. He's not my son! They called from the 469 # but left a different # to call back... which is 866-656-8484.
