Moto G4 Plus – Multiple Issues

I purchased the Moto G4 Plus phone on 8th Jan 2017 From Amazon. The phone has Multiple problems from day one.
1. The phone heats up a lot. It heats while charging. It heats even when the phone is not charging but I am surfing net. It heats so much that it becomes difficult to hold in hand. I thought some update from company will fix the issue. But it is not fixed. Sometimes I fear that phone will explode. I am unhappy and Dissatisfied.
2. Touch Automatically Turns on and off.
3. Phone gets hanged while using. We have to restart the phone every now and then.
4. Phone Charges very slowly. The Phone losses charges in 3-4 hrs even if net is off and phone is kept idle without any use.

I took the phone to Motorola Service center. They repaired it. But all the issues still persists. I want to return the phone and want refund. Please assist Me.
