BMW given back, still broken, disrespect in emails

My BMW broke down 15th Dec '15, sent to BMW Canal Walk CPT, back and fourth with Germany unable to find issue during diagnostics (car under motorplan) eventually they spent R76503,74 finally fixed 4th Feb '16 (sent reports saying its 100%) and released it to be shipped to JHB Melrose Arch BMW. (currently living in Zim and flew to JHB to pick up vehicle on 12 Feb '16, spent R6000 for myself, hubby n baby). Drove it out of dealership in JHB to find same problem not resolved. emailed BMW and got on call BMW to assist (Mechanic drove it and found same problem). took it then to Clearwater BMW JHB, where it is currently now. (going through same diagnostics again like in CPT). then had fly back to Zim-Harare 14 Feb '16 without the car, spending another R6000 odd on plane tickets. Now back and fourth emailing BMW to complain how they put our lives at risk, giving us an incomplete car whih they said was fixed (im 30 weeks pregnant, have a 1 year old daughter and my hubby) to drive from JHB back to Zim could have had an accident, for us to waste Thousands of Rands, when they said we can pick it up. and now Dudu Khumalo (Bmw customer servicer in Midrand is ignoring my emails)
