Poor service and non committal promises

Since I lost my fibre communications Saturday Openserve sent two technicians out Saturday and Sunday. Both did not fix the issue. First technician on Saturday promised to come and fix the fibre early today, seeing as I work from home. Second one did not know about the first guy and when I told him he decided to leave it to the first guy. Needless to say no one has still pitched at my home today and I have been without fibre now for the third day. Asked Afrihost to escalate from their side, but no response so far from OpenServe.
