Rude staff

I need to lodge a complaint about the very rude receptionist at intercare Fourways her name is Alma. She argued with me when wanting to put me through to the nurses when I need some resolution after paying an enormous amount on Sunday and none of my symptoms have gone yet my medication is finished. She argued with me and told me to listen to her when I told her the nurse can't help. She put me on hold for 20min then comes back and tells me the nurse can't help me (like I told her) she is disgustingly rude to be dealing with sick people. She now said I'll need to pay to see the Dr again. This is all just unacceptable no GP charges when it's under 5 days of seeing them and worse to be spoken to like that by the receptionist!
