I have submitted my sony xperia c4 dual to sony service centre-fortune, pradhan tower, 5, main road, ranchi, jharkhand due to abnormality in touch pad . Since i have submitted my phone on 4th of july 2016 with a assurance of getting my phone repaired within 15 days but till date it is not available to me.On asking from the service centre they say that the touchpad is not available in thier stock.After going to service centre three-four times they say that the phone will be provided to you within 1-2 days but its 28th of july and i cant get my phone.Even calling today they said that the touchpad of your phone is not available and again gave me 2-3 days time to recheck to know that the phone is repaired or not.My phone is in warranty and they are just making me revolve around their service centre again and again to keep checking.They also assured to provide me a new phone but till now i cant get new phone or even my old phone which i have submitted lumpsum a month ago for repair.my reciepts job no. w[protected].
