Miway is messing me around

hi, so my car was affected by hail damage etc, fastforward the car is at North City in JHB. The guy who was supposed to be assisting sometimes wouldnt answer emails etc, Brenton, ok no biggie, but heres the part that is really getting to me. The rental agreement has been terminated early, no idea why! 2ndly , now im being told that PG Glass is still waiting for the windscreen, I'm irked because I called Miway last year December to avoid exactly this. The lady from miway is trying to assist but is struggling to find any info, claim c***
