This is a corporate plan 499Rs/- having 40GB per month. For April 2018, I never received 40GB data into my account and all I am left with is previous month's left over data i.e. 25GB
CURRENT PACK DATA is 0GB (No data credited to my account in April)
DO NOT SAY, that I consumed 15GB data in 4 days and 40GB data is already credited. I am attaching screenshots to prove 40GB was never credited AND my usage in April is less than 3GB.
