Dear sir,
This is please to inform you that, my mobile redmi2 white color is in under warranty. My mobile display is not working so, i submit my mobile at your service center in ff11/ff48 at a-wing trident complex, vadodara, gujarat. My jobsheet no. - js[protected], on dat of 31st may 2016 and return dat is 13 jun 2016, but their is no any update for me from your service center and when i call at this center than they tell me thay want 10 more days for conformation. So i think their is no any person to help customer and also no responsible head for help to customer. This is my suggestion for your company please change your service or close the service center because their is no any responsible person at their. And they have no value of customer.
O please tell me what i do...?
