Motorola — Manufacturing defect in mobile

Address:

Gautam Buddh Nagar, Uttar Pradesh

Motorola is just fooling their customers. they are not using genuine parts. in almost 5 months, i have visited service center around 10 times but my issue is still same. they are not doing anything to resolve it. My phone is hanging, slow processing after the change of motherboard even. Motorola is just giving a excuse that they dont have the replacement policy but its a manufacturing defect than what is the fault of the customer. Somebody pls help
