[Resolved]  Micromax Informatics — Overheating, network issues, call cut automatically, touch not work

I bought the mobile (E455-black) on[protected] from that date i feel the problem of overheating, call cut even in an emergency call, sometimes touch is not in working condition, network is not available and so on. Within these short period, i gave my phone for repair 4 times. No change. Last time take 25 days for the repair. Still there is no change. Nowadays my friends are not call me because of these problem. I am a cancer patient also. Sometimes i want to call my doctors urgently. With this phone i can't connect with them. I again gave my phone for repair to m/s tech beam on 24.05.2016. Please consider my complaint and solve the problem as earlier as possible. I humbly request you to change my phone.
