I have serviced my mobile. For headphone jack problem, visited a store for service, customer handling explanation on problem and they explained some technical fault its quite interesting. made job card for service and the said maximum 8 hrs it will take a service, I gave my mobile and they done a service within committed time.
As per the commitment and customer handling. Way of presenting the issue clearance its quite interesting. Overall good. Feel better place which compare with others which I had experience. Cam refers others good keep it up
