Maniac takealot driver

I was driving On the M5 heading towards kenilworth,athlone At 1pm on sunday 3rd March, heading towards southern suburbs cape town.My car is clearly marked with a baby on board sign.I was driving just over 100 kmph when a takealot van drove up behind me and started flashing his lights at me to move out of his way. He was so close behind me that should i have braked even slightly, he would have driven into the back of me with my baby on board.when he eventually overtook me,he must have been driving 120 to 130 kmph. Not acceptable.he put our lives in danger.His registration was CA426781. This query has been ongoing since the beginning of March with still no resolution as of yet.The query has gone through the hands of Taahira Salie,tamille davis,Tshepang Oageng,Melissa,Mandisa N.I was to know what has been done about this situation and want it escalated.Yout driver could have cost 2 lives,one of a baby that hasn't even had the opportunity to live yet. Do your deliveries take precedence over other people lives?
