Micromax — Phone not working even after being repaired by Customer center twice

Address:

Gurgaon, Haryana

My phone IMEI M_imei1:[protected], which was purchased in Jan, 2015 has been repaired twice by the Micromax Service Centre, MG road twice but the same problem crops up again and again. The issue is that there is a network issue the data network 3G doesnt work, the display and side on power off button do not respond and hang. Also the sms has an issue, the outgoing sms are delivered hours later . Same is the case with incoming sms they are received later. When I checked the issue with Airtel (my service provider) they escalated the issue to the highest level and it was found that this was a phone set issue. The dispaly hangs several times and phone power button hangs always.
