Services cut without being informed and still no internet??

My service was cut on Friday. I logged a support ticket on Saturday. I kept following up as I was told that the issue was with SADV. I informed Afrihost that I require urgent internet as my son is busy with high school exams and needed access to msteams. I am also working from home and also needed internet asap! I was told that they were waiting for SADV to respond. Yesterday I phoned SADV and was informed that they no longer provide fibre to our area and that Afrihost needed to inform me. I thus no longer had fibre, our services just cut and no one let me know about this. I then phoned Afrihost and was on hold for about an hour. The tech support told me that our fibre is now with Vumatel but that they cut our services in error and that I must give them an hour and then our services will be up again. Surely between SADV, Vumatel and Afrihost they need to inform their clients when these changes happen?! This was at 12 in the afternoon yesterday. Our internet is still off. I logged another support ticket and was told to wait until we hear back from whomever it was escalated to. This morning once again, tech support tells me that they are waiting for feedback from SADV even although it was confirmed yesterday that they are no longer our provider and its now vumatel??? Can someone please assist us in getting a proper response as to why firstly we were not advised that our services are being cut because SADV no longer provides fibre to our area and secondly why Vumatel also cut our services then if it was meant to go over to them and I have paid every month???? I have been without internet since Friday and these half responses that I am getting from everyone is not helping at all!
