Southern Implants - No after service

I had an over R60 000 implant procedure done, which has failed. I have sent Southern Implants a message via their website to enquire what the process is from here. I have received no feedback from them. I then called in and a lady told me they do not deal with patients. She transferred me to her supervisor, Juanita who did not allow me to state my problem before interrupting me. I advised her that I was upset and trying to explain something to her and her response was that she was "also upset". I have subsequently dropped the phone on her. It seems okay for them to make me pay thousands for materials which break, but when I need help afterwards there is no after service.
