Hero Motocorp — i am complaining about achiever 150 new model rear brake system and about low width of rear wheel

Achiever150 new model's rear brake system is unbalanced. It makes the bike sleeved and i have been fallen down twice and have injured. I also make complain about the low width of the rear wheel. I think it is a massive problem. Hero moto corp should have to pay attention on this issue. It causes two massive accidents to me and i have been badly injured and my bike has been damaged badly. So i honestly request to hero moto corp to take necessary action immediately to maintain their brand value especially the bike like achiever 150 new model.
