I used the internet at night continuously - (i.e. from 11:30 p.m. till 1:00 a.m.) but my Anytime Data usage (11:30 p.m. – 12:00 midnight) cannot be seen on the data usage record.

If the usage from 11.30 p.m. -12:00 midnight is less than 300MB it will only be recorded at the point of when the session gets disconnected - (i.e. when the device is switched off). However, it will be deducted from the correct Data quota. The usage from 11.30 p.m. -12:00 midnight will be from the Anytime Data and the usage between 12:00 midnight- 1 a.m. will be from the - Night Time Bonus Data.
