Hyundai Motor India — quality of stereo is not up to mark

Address: Bathinda, Punjab

I have bought EON megna+ from northern motors Ludhiana on 27/5/15. It's stereo is not of good quality. It hangs every two days and hang over finishes only when disconnected from battery power.please do something. I thing there is manufacturing defect. In that case, can it be replaced from bathinda raja Hyundai motors as I m now shifted to bathinda from ludhiana. Parveen Bala Email [protected]@gmail.com Mob [protected]
