After 2 days i visite this serivec center they told phone network cable problem and they repair my phone and they advise me i can sell my phone in olx that good for me (This voice recording send by mail in your main service tem). After 2 day the phone same problem is occure. 6th feb 2017 i submite my phone and they give me old job sheet (I send photocopy). And i complain against this matter.
One day i received a phone call in your official service centre with conference air voice service center and a told saturday i collect my phone. Saturday visite service center after 2:30 pm but that time service center closed. Monday i visite this service center and they told my they can't know that the phone is repair or not they told 2-3time circling service center then give u, because i complain in this matter. 21/02/2017 tuesday i also visite air voice service center to collect my phone. Before i call service center contact no and they told my phone is repaired and collect. But i collect my pbone they give me my phone with out repair and they told me they can't repair my phone. Whene lenovo main office call me with conference air voice service center they told saturday (18/02/2016) i collect my phone. But tuesday they collect my job sheet and give me my phone with out repair and they told me they can't repair my phone. So i not collect my phone and allso my job sheet.

9th month time to buy my phone and 3 mounth or more time the phone in service center. So meny time i doing mail or phone call in your lenovo support time but they can't solve my problem.
Still now i visite 20 or more time in this seivice center. Everyday i cannot visite because i do a job and my job time period 10am to 6 pm and 25 km away my home.
