Sarf Trading — Mobile is not repaired and returned

Address:	Chennai, Tamil Nadu, 600007

I have bought sony xperia cs ultra dual white mobile from e-bay.com with one year warranty. After 9-10 months my mobile stopped working so as per the warranty card i called the sarf trading customer care and they asked me to courier it to them and they will repair it and send it back to me. The courier has been delivered to them on 27th october 2016. To my surprise they said that the mobile was water locked which is not at all possible at my end. When asking for the proof about water locking they refused and rather said to visit their chennai office if i need proof. Still i haven't got any calls or emails that i'll be getting back my phone asap. If you guys don't return my phone within this week i'll be taking legal actions. Please do send me email or receive my call and confirm that i'll be getting it back within this week.
I must suggest that you guys need to improve your customer care service or else close it.
