Xiaomi India — disappointed with the service provided at the service center

Bangalore, Karnataka, 560043

I own a red mi note 6 pro. I bought it 2 months back. The receiver speaker is not working. I went to the authorized service center at kalyan nagar bangalore 4 times and they were not able to fix the problem. It's highly disappointing and frustrating to waste my time at the service center. The engineers are not able to solve such a simple issue.1 st time they said it was a software issue and fixed it. Within 7 days same problem. Nest time they said it was a hardware issue and need to be fixed but part was not available. Then when i went they said it was problem regarding setting fixed it again same problem was repeates within 1 hr. So i am already frustrated with the service.
