Not working router for 5 weeks

Poor service, not care type of Supersonic management, calling everyday with NO assistance. I have a router with constant intermittent signal that goes off every 20 minutes. Keep rebooting, restart and resetting but still not working. I call everyday and open a case but the consultant close the case without investigating or assisting. I got assistance from a kind consultant (Lesiba) who tried to assist me but couldn't get support from the line manager who never listened or willing to assist. I tried every way to get assistance but SUPERSONIC doesn't have empathy and willingness to assist. I have registered 3 cases with them for escalation however no one called me to assist even when their own policy states that they will attend to your case within 48-72 hours. The company doesn't have good customer skills and there is NO difference between them and Home affairs' or SASSA offices. One will expect a proper great customer service from them when everyone is working from home but NOT with them. The router has not been working for the past 5 weeks and i spoke to close to 50 consultant and no one is willing to help. I don't even want to mention anything about their technical support who will just tell you that the tower is down without even verifying that. the case reference "CAS-950945" number was closed without even look into the matter and the other (was not given a reference number) was not even attended to;
