Poor customer service

Hi, I want to complain about the level of service offered by C fibre. The service is so bad and their service personnel do not seem to communicate. They send a subcontractor to your house with no clear instructions. My contract with C fibre was cancelled by mistake, I was told. I became aware when there was no connection. I reported the issue to them and it took 2 days to figure out the problem. I was then to complete the subscription form and submit. A week after I submitted the subscription form, they send a technician from metro fibre to change the fibre box. More than 24hrs latter there is still no internet. I then phone their call Centre again, and they do not know what is wrong, they will escalate. My question is don’t they have a procedure on how to connect a user.
