Pathetic! please save yourself from these guys.
Bought Nokia Lumia 820 by these guys and believe me these are looters.
Galleria Delhi Elctronic Shop: After I bought Lumia, this guy opened up the box and started sticking something on the phone, I asked what is this and he said ' maam screen guard" . Then when he was done he said, so the total is x+400 I asked why 400 and he said because I added screen guard!!! Without asking me, informing me, telling me that it costs!! When I told him it's not done, they started shutting the shop saying late ho gaya hai etc etc...I just took it and came back. But avoid these guys, you will find more professional guys just downstairs or any other place
