dear sir/madam,
Recently the internet speed on my mobile phone has dropped extremely beyond tolerable limits.first the speed used to be as high as 35KB/s-40KBytes/s but now speeds never cross the 8KB/s mark.why is it so? is the company upgrading or is on a maintenance or repairs? whatever the reason be i am experiencing this since the last one month.I hope you executives take it seriously and put in some efforts to improve the service to the level it was.I live in mumbai.
I hope you take this problem seriously and improve the service or else I am planning to switch to some other network operator thst provides better service.

REGARDS,
Sohellman.
