I want to cancel my contract with Telkom if no solution to my problem and I am NOT willing to pay cancellation fees!

I have a big problem with Telkom! As from November 2021, I noticed that my router periodically loses internet access. I would see on my mobile devices that it says “connected without internet”. And this started slowly but to this day it is a daily problem! I called Telkom on 12th January 2022 to explain the situation and after a couple of attempts (speaking to useless and no-knowledge service champions) I spoke to someone who seemed informed enough. After that call I received a case number (***2). On Friday 21st January I received an sms that my case was resolved, and while I was reading that text, I still sat with the “connected without internet” problem. At least once a day, this happens for 2 or more hours. This past Friday, there was no internet all day and even on Sunday the devices still said “connected without internet” for over 6 hours. I called Telkom on Sunday morning (to enquire about cancelling my contract with them) and spoke to Thandisile Msawuli (email address: ***) who was brilliant and explained to me that I would need to pay over R1200 cancellation fee. But why should I pay such a fee when I am getting a bad service from the company? All it takes is to get a Tech person to come to the area and assess the situation, instead once you call Telkom you get a case number and few days later they tell you your case has been resolved. I then went to the Telkom store in Liberty Promenade and explained to the lady (exactly the words of the telephone consultant) that LTE has a weak signal in my area (i.e. Mandalay) and that I would like to migrate to All Net. She told me I CANNOT perform a migration from LTE to All Net. She took down my number and said someone would call me to assess the situation either that day or Monday, and today is Tuesday and no one has called me. She refused to take down my name. I want to cancel my contract with Telkom if everything has turned robotic and that no one is willing to come to the ground to assess the situation. And I am not prepared to pay a cancellation fee because I always pay on time, never been chased for payment! I work from home and this is inconvenient to always be unavailable for over 2 hours every single day!
