I Had a Bad Experiecne in Flipkart. I Bought a Blackberry Z10 Phone in Filpkart.But That phone has a so much of complaints like
1. Sim Slot not working proberly
(If the I put the sim card means it will detect and after few minutes it will display unknown error in network details. According that I changed my sim(new sims from my network operator) twice in a week.
2. Battery back up is low
(The Battery shows fully charged, But its switched of with in 3 or 4 hrs . Due to this I will reboot my phone 3 of 4 time in a day.if its switched on its shows 0% battery. this is worst bad experience.

I preferred the Customer Care Centre of Blackberry.
They Doesn't Repair the Sim Slot Problems.
