Reliance Jio Infocomm — jio usage

I am very cinfused regarding my usage on jio. I have a 91 day package that allows me igb data per 24 hrs. On 6th jan i received a text stating i had used 100% of my 1gb allowance and my high speed would not be reinstated until 2am on 7th jan. This indicates that my 24hr usage allowance runs from 02.00 am each day? Is this correct?
If so then something is definitely wrong as today 10th jan @7.06 am i received a text stating i had used all my high-speed internet and will have nothing until 02.00 on 11th. As i was in bed with all my devices switched off between 11.45pm 9th jan and 06.45am 10th january i could not have possibly used this amount of data. No one has my secure password.
My number is [protected] please provide breakdown and details of when my 24 hr period begins and ends as i am totally confused now.
