Sony India — cheat on estimated bill for repairing xperia m2

Address:

Mumbai City, Maharashtra

my mobile Sony Xperia m2 fell into water but only damage i noticed after checking everything was network drop & camera error (patchy display but it became normal after a day) so I went to Sony mobile service centre, dadar, mumbai they told me it can not be done under warranty as water damage voids warrenty, I agreed and asked about estimate bill for damage repairs & they told me that it would be 15, 500/- where as I brought same new mobile in 14, 500/- so i took my mobile back, came home & switched on and checked camera and it got started if i wouldnt hav taken my cell back, they would have charged me 15, 500 for nothing
