Hi,Since 20th December my account is not showing up any session history, nor change in bytes used. I spoke to CC people they said its due to some technical upgradation at the servers. I am wondering now as to what is the actual data usage remaining. I hope they don't jumble up my usage by mixing night usage with day.I have even checked on my two friends usage, even they are not changing. they are having different plans than mine.How about others. ?? Is any body in delhi facing this. Now what to do. IS this the actual usage or there are any chances of the usage suddenly shooting up in case they do a batch update of sessions??? :blink: By the way do we have a carry forward system of unused data in 590NU plan.
