Xiaomi India — delayed in installation of tv

Address:

Gota, Ahmedabad, Ahmedabad, Gujarat, 382481

I have purchased Mi Tv 43 inch on 4th march 2019. I have Appointment for installation on 6th march 2019.
But no one came for installation. When I talked to customer care they talked very bedly and told they have rescheduled Appointment for the next day 7th March 2019 and even today no one is came and when I talked to customer care they Answered the same that they rescheduled for the next day.
This is really bad service experience from Xiaomi india.
No one is answering, no one is solving the issue.
I am afraid that they will do the same duing service.
