Vodacom fiber not working for over 5 months

I had vodacom fibre for over 5 months and it has been hell from the 1st month. I struggle with connection every single month and the issue never gets resolved. They have given me 4 different backup simcards and ****les and they all don't work, I've had downtown which was not credited and ticket closed without even contacting me. I've logged complaints via emails and telephonically, they have all been ignored! Emails were sent through to *** & *** but they do not bother to contact me back. I have spoken to the retensions department to cancel this appalling service, but they refuse to cancel and I keep being promised that it will be sorted out, but nothing has been done. I have spoken to the following agents and managers from retention and they promised to call me back but they have never bothered for over 3 months, their names are as follows: Azande Seshan Jordan Sahir Heerlall CJ Celine Emily Aricksamy
