Extremely disappointed

It is with great sorrow that I write this review. I have been a Vodacom client for the past 24 years. I have had problems with me newly installed fibre line from day one. It seems as if all my calls fall on deaf ears. Every time I lodge a ticket nothing gets done. I have had an open ticket from the 13th of August 2021 till now. Today when I called the service consultant I was cut off because I was complaining about the service. My question is what I am to to to get my problem sorted. The person from Vodacom that contacted me this past week told me there is nothing wrong with my fibre connection. Must I resort to legal action before someone will take notice of my problem or something more drastic perhaps. I am at a loss at this stage. Can anybody from Vodacom please contact me and tell me what am to do.?
