Motorola Solutions — My phone is not served well

Address:

New Delhi, Delhi, 110044

Recently i have visited one service center in govind puri, okhla phase 2 near royal enfield showroom, new Delhi. it was my second time in that service center for the same complaint that my phone suddenly get dead and every time they change my phone's motherboard and they did not provide any proof that my imei number is changed .
And now the problem is that i cant hear anything when someone calls on my phone they can hear me properly but i can't . now i have pissed off going again and again to that service center because they are unable to fix my phone as it gets dead after 2 or 3 days from service every time or any miscellaneous problem arises. it has been only 2 months when i had purchased this phone.

so i would request you to replace my phone or return my money back.

my imei number is [protected]
