Dear
All..

I was a big fan of xiaomi.. I bought 3 phones from xiaomi as well was flipkart.
But company after sales service is soo poor that you wont imagine. I want replacement of my product.

Last day (Yesterday) my phone got switched off. I thought that it needs charge i turned it on and saw that battery is in 65%. But the touch is not working.
I visited local service center, and told them to fix as my handset is in warranty.
They told me to pay. I got stunted and after so many hot discussions i agreed to pay as customer care number is always busy and out of reach.
They given me budget of 2700 for the touchpad. And took 3 hours. After that they told that we cant repair as your board is damaged also and it will cost more and more..

They didn't even provided me the job sheet and returned my handset to me and told that sir now your set has turned into a pg handset any service center will not give you warranty now.. What to do??? Now...

And as a result of being visited service center now my display has also gone.
So first the problem was touch response and now the problems are

Out of display and of of touch, '

I want replacement of my product.. Nor i will be a hard detractor of xiaomi and never ever buy your products, again, in future.

Wish this is a escalation, please help me.
