[Resolved]  Motorola Mobility — service center issue

Respected sir/madam

I aditya rawat have one of your moto g4 plus mobile in which i recently faced charging issue as it was covered in warranty i took it to moto service center i. E near mdda complex dehradun they kept my phone for 12-15 days and dint provided me with a spare phone to use. All that went well as i received my phone finally after 12 days but i realized that my phone started having other problems within days like
1. Finger print sensor was not working
2. Phone vibration was not working
3. Heating issue
4. Camera quality showed up too b very bad
The service center said that they have changed my phone board as it was the main issue and gave me a new imei number.
I was not back home so was not able to report these problems to the service center and now suddenly my finger print sensor stopped working completely. I took my phone back to the service center and they kept me waiting for hours and in the end of the day said it will take 15 -16 days for the repair so i asked for a spare phone to use they gave me a low grade phone that is also not 4g.
I submitted my phone on 7th oct 2017 and called them to ask about the status of my phone they dint inform me by them self for weeks i called after 21 days and they said that the parts they have ordered is not available with motorola company and so i have to wait another 3 to 4 weeks i argued with them and said that i will come next day and i want to see my phone ok but at that day i was not able to make it to the service center and now after 7 days i called them back and they said that they have packed my phone as it was and want me to take it back as they cannot provide me the part which my phone needs.
I have emailed every possible moto service people but dint not got any proper response. What can be done please let me know i need to file a complaint against moto and this service center.
