Sony — Warranty period but company is charging

Dear,
Sir/madam,
I bought a sony phone last year on date 21april2015.It's still under warranty.
It rained a little when i was in mumbai for some work.My phone stopped working suddenly.
It is very surprising to note that a few minutes of rain attached the phone to an extent it stopped working completely.
Now the services center is not saying the actual amount it may be rs.1000 to rs.3000 to get the phone up and running which i honestly think is too much for a 10000 range phone.
Please see to the matter and provide me with a good resolution.Let sony stand up to it's reputation.If my clients resolution not solve in warranty period i send a letter to consumer court and high court. Model no d2212 sony xperia e3 dual.
Thanking in anticipation
Best regards
