Pathetic service sees C Fibre client without internet for more than eight months!

My sister has been extremely busy with projects for the last eight months and she has not been connected to C Fibre Wi-Fi all that time and after phoning their call centre numerous times over the last eight months, C Fibre's pathetic customer service representatives have told us that there is no recollection of our numerous calls and that they have always hinted that they would send a technician to sort out the problem but they never have. While the technical department was striking for two or three months the so-called customer service agents would say that they are forwarding us to the technical department only for us to realise that they had forwarded the call to another customer service agent and we could hear laughing in the background as they didn't care about the fact that our internet was down one bit. Eight months later without C Fibre internet, my sister has emailed C Fibre to ask for a refund from the last eight months and to cancel her contract with them - to no response! This is absolutely pathetic service from Cell C/ C Fibre and is unacceptable!
