The grab app not provide customer complain about driver attitudes. I want to complain one of my horrible teribble and the most unsatisfied grab car experience. The driver was so rude and not explaining well about grab policies about 6 sitter car. He told me rudely about 6 passenger car are not allowed any groceries or goods in the car because my friend and me totally 6 person. He can just tell me nicely and cancel the reservation and I can order the 3 car 4 passenger and with the groceries.
