Micromax — Charging issue

I have purchased micromax knight cameo A290 on 14/10/14, from last 15 days its not getting charged, today when i visited micromax service center (in Secunderabad, paradise) they say that the charging slot pin is misplaced and its not covered under warranty and service cost will be 1820 approx whereas phone cost is hardly10000. Its a new phone and somhhow they cook some stories to charged their customers. Its not even more than 6 month and phone is down, I have read several reviews and many people has faced this issue, still company is least bothered and service people dnt even know manners and are most difficult to talk to. In short, this shows micromax standard. Please help in getting my phone repaired.
