Micromax — no proper service when i paid full money for service!

Address:

Indore, Madhya Pradesh

My cell screen was damaged and i went micromax service centre and i paid rs.2100 and they have changed the screen last year..but i was not knowing after 1 year that inside screen the dust will get collected and i wont be able to clear it..when they have changed the screen they have not kept the rubber part which stops the incoming dust into the screen..and i came to know this yesterday!! bad service!!
