My Lenovo Smartphone Model A7010348 had gone faulty and was deposited in authorised service centre on 2-1-2017. The Job Card No is SOINO[protected] and IMEI is [protected]. They have given 06 Jan 2017 as expected date of delivery. It is 09 Jan 2017 and the phone has still not been repaired. Every time I call the service center they ask for three or four more days to repair the phone. kindly do it on priority.
