Shocking service!!

I have reported my fibre issues to Afrihost who are my service providers. Afrihost reported the problem to Tesuco Telecoms (TT Connect) who still haven't responded. My question is WHAT WILL IT TAKE TO GET THIS PROBLEM RESOLVED?? I've had no service since 25 August 2018. it is now 5 September and they can't even give me a proper date as to when someone will come out.....this is totally unacceptable. Can we get someone senior to talk to another senior person preferably one that can speak and understand English!!
