A Reversal takes place when you were previously issued a bill for the wrong amount. This can happen when:
If this happens, we’ll correct it on your next bill by ‘reversing’ (or refunding) the whole amount of the incorrect bill. This will appear on your bill as:
Where xxxx will be the invoice number from the incorrect bill.
We’ll then ‘charge’ the new correct bill amount, which is just the same as calculating the difference. This will appear as extra line items on your bill but it doesn’t mean you are being charged twice.
Any credit or debit due will then be applied to your overall bill.
