Bought yu yunique 2 plus (Yu5012 model) on 20-july-2018. (Imei details attached as image file - please check the attachment file)

1. Installed airtel simcard. From first day, the incoming calls never come, the messages is "not in network coverage area". Then changed the sim to jio. Again same problem. I restart the phone and then for 5-10 min i get some incoming calls

The incoming call screen doesnt appear, dont know how to answer the incoming call. After 5-10 min again incomming calls stop - no network coverage isssue

2. Uber doesnt work. But when installed in other phones it works

3. Youtube app doesnt work properly

4. Every time have to restart the phone to make a call or receivce an sms

Finally after struggling with phone, on 5th october gave the phone for servicing in the following servicing center:

M/s s3 communications
No 76/11-1 (Ff), jaynagar, 3rd block, elephant rock road, opp rr gold palace, bangalore, karnataka

They said - "it just needs a software update and everything will be fine, if you have any issues, we will change the mother board"... They returned the phone on 8th october... Still the incoming calls do not come... They never tested in the first place... They just did some software update and returned the phone

Again went to the same service center on 10th october, they said, "we will again do another software update and this time also if it does not work we will change the mother board"...

How many times should i run around the service center? From first day this phone had a problem. I asked for replace, ment and they are not giving me a replacement.

This is my first micromax product and i am having a very bad experience with the product and the service center staff... Please tell me what to do?

What kind of product is this which never worked from first day and what kind of customer service is this?
