Respected sir, I bought A Intex mobile (INTEX AQUA Q5) from its dealer worth of Rs 5000/- only. for me 5000/- is a big amount. The next day I started using the mobile but it shows this massage '' Unfortunately Google maps stopped", OR "unfortunately camera stopped", every app shows this massage only. suddenly it shut downs, or some dim shade appear on the screen. I give the mobile to Intex service centre, (they were not responsive) they taken it and given it back after 2 weeks what they done I don't know. Problem is not resolved. I called customer care no response, what to do, where should I complaint this matter. Plz provide me info for solving my problem...
