If you are a credit customer, you can view your transactions by going to the My Account tab and selecting Invoices. You can then either download a PDF version or extract an Excel version of the invoice showing the transactions for that invoice period.
If you are a Prepaid Wallet customer, navigate to the My Wallet tab and select Transactions. Here you will be able to see your transactions. You can also select from the drop down to download transactions for the last week, or the last month.
