Complaint Handling Process 

Upon receiving your support request or complaint, our trained Customer Support Representatives will investigate the issue and will keep you informed until we have a resolution. Depending on the nature of the complaint, the time to resolve the issue may take a few days. We aim to resolve all complaints within 15 business days of receipt.

However, if you are not satisfied with the resolution you may contact the Telecommunication Industry Ombudsman (TIO).
