Pathetic service Supersonic Fibre

Most pathetic service. Been a customer for about 2 weeks now. Had decent internet for about one day. They had to reset my router at the tower about 7 times already, had to factory reset the router twice. Asked for a technician to come out to sort out the problem, but they ignore the request. (although the option is stipulated in their customer care policy). I've had a technician come out (at my cost) to check my side of connection. Nothing wrong. Service provider problem. The technician even said that he is willing to speak to the Supersonic technician to explain his findings, but nothing. Everytime I must reboot the router, but problem is not fixed. I've tried whatsapp, Messenger, facebook, phone calls. Same reply "we jave escalated your problem to the technical department". Don't think there is a technical department. Next stop wil be the Ombudsman
