Mi — mi band 3 hopeless service

Address:

SALT LAKE INFOTEL KOLKATA, Kolkata, West Bengal, 700091

Bought mi band 3 from amazon on 24th of january. I started using it in april. It got charged once and stopped getting charged soon after that.
First visit to mi center (Infotel salt lake kolkata) :i got it replaced fully and a new sealed box was given to me. I trusted and believed your company and brought it back home. The entire product was not working either it was damaged or your company creates products which work in fluke.
Second visit to mi center : the guy there (I know who assisted me but i would not take his name) fooled me after showing the product and said it is getting charged. I though i am not able to do it and i still believed in your company (How foolish i was) and brought it back home.
I showed to 4 5 people at home and office colleagues who confirmed that still the product doesn't work.
Third visit to mi center : i literally got pissed off after the again trying to fool me by saying it is working. Then i yelled at them and showed how it is not taking charge on any other points or by any other charger. After which i said i need to speak to your manager. And you manager very conveniently said the product can only be replaced it cannot be reimbursed.
Do you think i am fool to back to your center and waste my time on your unskilled and unmannered team?
I paid 20 n=bucks for parking everytime i went. I had to leave early from office for this simple product which you cannot make correctly after 3 times of wrong service?
My suggestion to your company is to shut it and first learn to make products correctly.
The harassment which i have gone through can you repay to it? You cannot even repay my hard earned which i invested in this product and your company talks about customer satisfaction.
Last time i visited your center was on 24 july after which i couldnt visit because i am not in the city.
Your company only has the product with you if you can do something just give my money back because you have ample time to fool customers but i dont have time to waste on such a hopeless product and service.
I will make sure that i pass on my feedback to as many people as possible and all the social platforms within my reach.
