Xiaomi India — Redmi 2 charging point problem and charging problem

I bought this mobile phone and was initially happy for two months. After two months the charge starting draining fast. Initially I used to charge once in two days. Then every day I must charge or the phone will switch off. Now after four months new problem has started. The charging point won't respond. I ran to the nearby mobile shop. He charged Rs.500 and told he has screwed the charging point tight and it is ok. But again problem did not get resolved. Now I learnt that when the green light is on it is not necessary that the phone is charging. The charging signal was not showing. Now I am frequenting the mobile repair shop. PLEASE DONT GO FOR XIAOMI REDMI2. IT IS DISASTROUS.
