B2X Service Centre, Guindy, Chennai — worst hell response to customer

Hello all
I gave my mobile iphone 7 to b2x service centre, guindy, chennai.
They are worst service centre in my life ever seen.
Instead of going to them better go and throw your mobile.
The people who are all working there never respond you. That won’t even pick your call. And they will not listen your words.

They are very worst character people, especially the girls working in that service centre, if you call them for status they will speak horrible manner.

They won’t give any report detail for the service you have done.
Idiotic and irritating people..
