Extremely bad service

We have been experiencing issues with our Vodacom fibre ever since it was installed. We called the call centre and every time we get promised that it will be fixed or send technicians but nothing happens. When we call to make follow up we get told that the case has been closed without any resolve.

We get reference number over and over again ***7 it was closed without the issue being fixed and SR*** still pending some I even deleted as they were taking space on my phone.
