Bad service provider

I have exhausted all communications that are available within my disposal,but as a customer I see been taken for a ride, I made payments n asked the service of my WiFi to be reinstated was told technicians are onsite but till this day my WiFi still not working, I've send emails n WhatsApp still no changes, whenever I ask for a refund I get no response because I cannot pay for the service I never used or received, These is their response since I logged the complain

Thank you kindly for your patience, please note we have logged a ticket with technical support to assist further with your query. They will contact you to assist further. Ticket reference ZF000C2VD, till this day no technicians on site or anyone who phoned me,
