Supersonic wort aftersales ever

Hi all, so after 2 years and a bit with supersonic my internet have been put off every time at this time of the year. Phoning them doesn't help because the all need to wait for a supervisor and asking theme that the supervisor must phone you back, you can rather ask the tree in your backyard because it will respond better than any of the supervisor's of supersonic. I have been without internet for the past 3 days now and like Friday sending them a whatsapp they do not even respond. So I got help from the technical support Lerato that ask me for my proof of payments and she responded that I must not give her 2023 payments that I certainly did not do and I have proof of everything I'm saying on my message. So I think supersonic is hiring people that only finished school at grade 8 and not higher because they can not read. Then I got hold of the technical team again late this afternoon and I ask for CEO Mr Terence Chetty or COO Mrs Shereen Rimmell email address or number and to put my internet on and I was told that they do not have authorisation doing any of that because there are no supervisor available at this moment, so how do you let people work and sort your troubles out if they can't do anything, as an old service workshop manager my number was everywhere so I could have help and show my customers what service is, now they are scared, ***ards is the right word actually. I hope that Mr Terence Chetty and Mrs Shereen Rimmell read this massage and phone me back for cancelation on the poorest service I have ever experienced in my life
