Despondent customer

I have been having connectivity problems for 2 weeks. I’ve called the supersonic call center 3x and spoke to a Thembinkosi(rude) and a Nokwanda (who sounded decent). A week later promises of having the technical support team come through are yet to be fulfilled. This has caused great strain to my as they online some days. I don’t even know who to write or call at supersonic as they only have 2 forums for communication,call center or WhatsApp (robot).
