Moto G wont uninstall apps. topic

Hey guys. 3 days ago I purchased a brand new factory unlocked Moto G in Pakistan. The problem is, whenever I try to uninstall any app I downloaded off the Play Store the phone shuts down and then the start-up screen is displayed after which the phone restarts back to the unlock screen. I did a complete reset to factory settings but the problem still persists. The version of Android is 4.4.2
I could return the device but its a hassle I dont want to take if one of you can help me fix the phone.
