Pay the hospital bill please!!!!!

I am begging you to pay my son's hospital bill from almost 3 months ago. Calls are useless. People say they will get back to me and not once has anyone gotten back to me. Emails ignored. Twitter ignored. I am out of my wits end and have received a final demand letter from Mediclinic this morning. The service has been ********** from Bonitas. 3 months to go and I will be out. Awful.
