No internet

I’ve been phoning supersonic for over 2 months now battling with the signal as I have 20/20 fibre with them but always has 4 up and 3 down.. On the 11jan21 I called to upgrade my account to 50/50 thinking it would be better which supersonic said it will take 4-5 days to activate which took 11 days. On the 21st when it was activated thinking my signal is going to be so much better it was worse..also on the 15th of jan I called to request for a technician to come out and it’s the 23rd and still waiting..yesterday at 16:00 my whole internet stopped working and called supersonic and they logged another call which is unacceptable and told me to wait another 48 hours..I then called customer relations and spoke to K/govender and which had the worst customer experience ever in my life as he was so rude and kept talking over me and I requested to speak to his manager as he kept chirping me over the phone..this guys should never work with customers ever..then I spoke to cherine govender the manager and advised her the whole story and she said she will get a technician to my house today and will call me at 08:00 this morning..it’s 11:42 and haven’t heard anything from supersonic and a technician..I’ve called twice today and they can’t give me an answer..I will not be paying my account this month as for a month I’ve had no internet...if I do not get someone to fix it today or tomorrow i will be cancelling with supersonic and also writing to all the papers about how terrible they are and no one should use them
