The first page of your invoice summarises your bill.
The ‘Calls‘ section lists the types of call made, and any associated costs. Any calls covered by a call package will not show here.
The ‘Services‘ section lists the different types of services you are being billed for, and the associated costs. This can include monthly recurring charges and one-off charges.
The next section shows the total amount for this bill. It will also show the total amount for your last bill, and the amount of any payments made towards this. The final amount shown is the amount due on your account.
