Hey @Anmol_2,
It can take up to 2 days for the information in My Account to reset properly after the billing cycle date. If you cancelled the Data Top-Up it should not be billed for the new cycle unless the invoice was already generated for this month.
The invoice should be available within a few days after the bill cycle date for you to be able to confirm this information under the Monthly Charges section of your bill.
I hope this helps clarify things a little.
