Well as Kasas@ said Abt wateen , Same happend wid me , in janury 2008 we paid 500 and did`nt get bil till 12 may,As i opened the bill it was surprisingly 40,500 Rs,I never used that much net as i was buzy wid my olevl exams ,And every month they sent that i have exceded the limit.Well after that in august i disconected it and joined worldcall once again and still for the septemebr i gt bill od 6,432 Rs and the bill showed i exceeded 3.32 GB well i had disconnected it so how can i exceed when im nt using it.
I m very much satisfied wid Worldcall im gettin 60 kb/s on a 512 kbps setup and the service is alos gud .
