We would like to assure our customers that we are working hard and doing all we can to minimise disruption. During these uncertain and challenging times, we recognise some of our customers may be impacted over the coming weeks and may be required to stay indoors and self-isolate.

We ask customers to reach out to trusted friends and family to assist them to top-up their PAYG cards. This will allow us to keep our phone lines free for the most vulnerable customers and emergencies.
