balance alert feature?

Hi, can you please amend this:

You can top up your account any time through bank transfer, PayPal or express bank transfer. The invoices are available immediately for download in the customer center. The ‘balance alert’ feature informs you via email or text message when your account reaches the amount you have determined.

Many thanks,
