After purchase, it worked fine for 2 months after that calls are getting dropped, I saw the network is getting reset automatically. Till date I visited 4 times MI service center after they repair it is working fine for 1-2 months and again the same issue is starting. I requested replacement, service center telling to ask customer support and customer support asking to goto service center, both are showing each other and wasting my time and money. I'm adding video for your reference.
Below are the job sheets from service center same are attached.
