GTI 7.5 Brake fault/ electrical unresolved after 1 year and 4 months. And just getting worse.

I traded my Gti 7 in on a Gti 7.5 last year. 400km on the clock took it back. Brake problem. It has been a year in and out Vw polokwane. January 2019 decided i had enough. Call Vw Sa. Since January till today tests had to be done and sended to Wolfsburg, Germany. Problem still not resolved. For 5 months Vw Sa could not resolve this urgent and life threatening problem. I must phone daily just to find out. Made over 200 calls to Uitenhage. Had 2 different spesialists involved. Karen at The Director of Vw Sa Dir. Scafer office said i must just wait for Germany with final answer. Well. My vehicle is used as a response mv. Saving lifes. This is one big accident awaiting us with this mv. Jason.
