I had free data rolled over (450mb) this month which was added to my new monthly allowance (250mb) to give a total of 700mb. I have used almost 300mb and my ID appreciate shows that I still have over 400mb left. However received a text today informing me that I had now used over 80 percent of my allowance. The rollover was from data given free as a World Cup promotion. Can I ignore the text and reply on the balances showing on the app to ensure that I don't get billed for additional usage?
