Billing without providing the service

My wifi router was disconnected on the 24 march 2023 without being informed. i followed up and was told that since i now have fibre installed they had to disconnect the router to avoid double billing, of which i get. the challenge is the fibre line in my area is not yet live and Metro fibre have no idea when it will be live. i asked vodacom to reactivate my router sim card while i wait of which they failed. after being on the phone with vodacom everyday, they promised to send me a new simcard and refund for the months i was not connected. even today i havent received the sim card and they continue to bill me for service not provided. All i want is for vodacom to send me a simcard and reconnect my router, and disconnect the fibre since is not yet live and refund me for the month i had no internet connection.
