Vodacom Fiber not working

In August 2023, Vodacom provided me with fiber. I called them repeatedly to get the internet to work on various devices, but all they would say was that they would send a technician, who would not show up until March 2024. After the technician resolved the problem, everything functioned normally until Wednesday, April 24, 2024, when my internet stopped working. I called them, and after a few hours, it only came back on Friday before going off again on Monday. Since then, I've been phoning them every day. Three calls per day, no internet. No one has phoned me since, despite their repeated claims that the matter has been elevated and that I would hear from someone. Since I work from home, I am forced to purchase data on a regular basis in order to continue working. Even so, it's not true , I've been getting sms from Vodacom saying that my internet has been fixed. Upon calling to terminate the contract, they requested that I pay a cancellation fee. They have no sympathy.
