Shocking Service. Duty manager refused to talk to clients

I have had a problem since early September. Nobody can resolve it and nobody calls you back. Today I asked to speak to a manager (because Supersonic Fibre doesn't have a complaints process - Which is TCF regulation by the way) and the manager (Lorenzo) refused to speak to me. Brilliant Client Service Manager skills. Supersonic were great in the beginning (just as we went into lockdown) but have steadily become the worst. Once you have you money you don't care anymore. Just like all service in SA. Guess it's what one has to eventually come to accept. Bet they won't even read this post. Time to cancel.....
