Poor Service from Supersonic

I app**** for a fibre line with Supersonic after my contract with Mweb went sour - another long story - on 20 January 2021. They promised that I would have a line within 14 work days of my application, but would connect me with a F-LTE product, within three days, in the meantime, at no extra charge. Every other day since my application, they have been sending me the same old electronic email reading "Your fibre line installation is still in progress. We will keep you updated on the progress" On 4 February 2021 they changed their tune to "We apologise for the delay on the installation of your fibre line. We would like to assure you that we are working on it and you will be experiencing super-fast internet speeds soon". Some 16 work days later I still do not have a line and there is no proof that they are working on it. The F-LTE product they promised also did not materialise. Yesterday, I phoned Supersonic and spoke to a complaints agent, who could not give me any reasonable answer to the delay on my line. When I asked to speak to her manager, she indicated that she was working from home, but she will get her to phone me by 18:00. She still has not phoned me and it is after 18:00 the next day. Everybody is screaming out to lift the economy during these trying times, but service gets worse by the day. Is it because management is driven from homes, or else where? I am very disappointed with Supersonic, after I was strongly advised to use them by my son. I live in hope that I will someday soon have a fibre line.
