Bad service

I am disgusted by your service, I have been having issues with connection since I joined your services last month. The fiber box has been changed twice already and still...Today I don't have connection at all and the agent is telling me that I have to log a return for the router as it is not working and pay R250. And I will have to wait for feedback from you guys and you can't give me a new router in the meantime because I will have to pay R1000. I have logged this issue almost every single day since I joined these services. And also to cancel I will be charged a cancelation fee. None of the options benefit me and I pay for the services
