These people absolutely suck. They will quote a price and after a few days either the part is more expensive due "miscommunication or misunderstanding" or they will spoil something in your phone and say that has to be replaced.
In koramangla 1st block there are these guys called Murali and Yogesh who have no idea on how to repair phones or ipads. They promise big, do all there R & D on our devices and screw up big time.
Kalay is another joker in the organization, who says he is Customer relationship manager. He is the worst person, no value for word.
All I would say is everyone is tempted to go to them for "3 Month" warranty they offer. Trust me, you can get the part replaced from outside 3 times in lesser money and time spent.
I saw them break an Ipad camera and later call the owner to explain how the lens is damaged. When they saw me noticing this behavior they tried covering up, Apple sends 3rd grade products in India. Blah blah.
If you still want an adventure, go to them. You will not be disappointed.
