C Fibre striking in April leaves homes without Internet

At this point in time my sister who is with C Fibre and Vumatel in Mowbray has been without Internet access for a week and at my houseshare in Claremont where we are with C Fibre and Octotel we haven't had Internet access for two and a half weeks now! We have been phoning for the last week or two for both houses and they only tell us now that the actual C Fibre department has been striking since the fourth of April 2019. This is after last week when we phoned three days in a row and they said that a technician would call us back the same day or the next day to make a time to come and fix our Internet connection problem at both homes. This is absolutely unacceptable and pathetic customer service. Also my sister signed the contract for and has been paying for 20 mb/s upload speed and 20 mb/s download speed on Fibre. They installed 20 download and 2 to 5 upload speed and this hasn't been rectified for several months despite numerous requests and phone calls in this regard.
