Lenovo — overheating of battery & draining of battery within 1 hour of 200% charging - switching it off

I had purchased lenovo k5 note on 11 november, 2016 form flipkart.
However from long time i am facing overheating of battery and draining of battery within 1 hour of 100% charging. I had been to lenove service center in ghatkopar where they informed me the phone has only 6months warranty and i have to pay rs.2250 for repairing battery. After consulting lenovo support center over emails i was informed to go to vashi service center as my cell has a warranty of 12 months & not 6 months. I went to vashi service center and got my cell repaired within one day. Now after repairing the battery issue things have gone from bad to worst.
The cell phone heats up while charging and within half hour of 100% charging the cell switches off and i cannot charge it again as the phone is too hot to even hold in hand. Seems there is manufacturing defect.
