Xiaomi Mi India - Huge Delay in Service

Hi,
It has been an extremely frustrating experience with Xiaomi customer service so far. I reported the TV Display issue on Dec *, **** and was promised ** days of turnaround time to fix the issue. Then, it was extended to one month and the deadline date promised was - Jan *, ****. Despite multiple follow ups, it was NOT resolved within the new deadline of * month.
Finally, the TV arrived yesterday - Jan ** (which was more than *.* months from the date of report). I was excited to get a ** inch TV as a replacement but disappointed when I heard the sound of the TV. My concerns are:

*. Huge delay in resolving the issue (that too not completely resolved yet).
*. It is definitely NOT the Dolby sound in the TV as there is no Base. I have been using a ** inch MI TV for over * years and it sounds way better than the ** inch TV that i received.
*. I am not sure if this is a brand new TV or a refurbished one.
*. The TV box was not sealed when it arrived. The box had already been opened before.
*. There was NO TV Remote with the TV.
*. There were NO Table Stand Bases.
*. On Jan **, I received a text message stating - "Dear Xiaomi Customer,
As discussed, we request you not to accept the product at the time of delivery. The order will be automatically cancelled and a refund will be processed within * days, once the product is returned to our warehouse."
