Fearing for my life with Help First, Emer-G-Med

In the morning i was involved in a multiple car accident, 4 vehicles was involved in this. Help first tow trucks with Emer-G-Med on the side door came out and stood by, from the people that was involved in the accident we called Metro and the ambulance to come out to assist. after waiting for a couple of minutes we (involved in the accident) discussed between our self why they take so long? in this a guy came up to us heard what we have discussed among one another and said that he canceled the ambulance and also the SAPS as he doesn't feel that it is necessary for them to assist and to come out (first of all who gives him "Help First, Emer-G-Med" the right over me and my health as i have medical aid). I then asked him why he cancelled the emergency vehicles as some people here needs to be examined by emergency personnel, he then told me that i need then to call again. i said to him but i did and you cancelled it. he then rep**** to me that i need to "shut your ****en mouth" I asked him that why is he cursing and that its not professional where he came up in my face and told me "what are you going to do" in a very threatening manner. Fearing for my safety i turned and walked away and he then again said while i was walking "yes you ****ing **** i thought so" This was the most aggressive person i ever met in my life representing Help First, Emer-G-Med. his vehicle was reg: FS 52 LF GP
