Xiaomi India — Faulty speaker - Spare part not available at Service Centres

Address:	Bangalore, Karnataka, 12200

There was problem in the speaker of my MI5 and I had sent it for repair at MI authorised service centre..I was told to check the status next week..Next week, I was told that the spare part is not available I must check next week..
This way I followed up every 4-5 days and each time the same reply that spare part is not available..
Finally, I have taken back my phone and using it either on speaker mode or with handfree cord..
Very depressed with after sale service..Seems made a mistake of trusting a Chinese company
