I received a call from TCS from this number for my test reminder before the test on 10th feb 2013.

021-34321675

You may try to contact them at this number. I haven't called them yet, as I am not very hopeful. As per my guess atleast 200+ candidates cleared the test from Karachi alone with some scoring as high as 65-70 marks whereas I stand at just 50 marks.

I been almost 20+ days since the result was announced, I am guessing the successfull candidate would have been called up TCS by now.
