Cap credit and data allowance are dealt with separately.
Consider the following scenario:
Let say you are on a $49 cap which have $550 credit for calls and 1.5GB data.
You exceeded your cap credit this month, let say you have used $600; then on the bill you will see $600-550=$50, you will need to pay $50 on top of your $49 cap.
You also exceeded the data quota as well, which you have used up 2GB of data (500MB extra), vodafone charge excess data rate at $0.50 per MB, so it will come to: 500MB x0.5=$250.
In this scenario, you will receive a bill $49 cap + $50 call excess + $250 data excess=$349
This is how it works.
Now, come back to the vodafone record, do not worry about the first amount column but the second one. In your case $8.26 and $0, only amount on the second column will be added up to your bill.
So if you only exceeded your cap credit but not the data allowance, you will only pay your cap charges + excess call charges |
