Sony India — Sony xperia z3 not working, asking for huge amount (25k) to repair it

I bought Sony Xperia Z3 (Model: D6653 white colour) on 26 Jan 2015, for Rs 45k+ 1.5k insurance, its huge investment to buy a smart phone, one expect it to work atleast for more than 1 year, but just after the warranty period ended, in Feb 2016 it stopped working, went to service centre, they are asking Rs 25k to repair it. Now who is going to invest 25k on it when the present phone price has dropped to 27k, its completely useless, are they making fun by asking 25k for 27k phone to repair.
