Micromax Informatics — No cellular network after three times rectification in authorised service centre

Address:

I purchased micromax nitro E455 on 31Jan16. since then this is third time i'm facing the same problem of no cellular network. your kanpur nagar service centre has got no answer about that. As a defence personnel we don't have that much time to visit your service centre again & again for the same reason. please intervene and give me some solution by replacing the obsolete one or replace it with good one micromax smartphone for which difference amount will be incurred by me. Thanking you, hoping the best from you. Jai Hind.
