Shocking communication and service delivery

This must be the worst service I have experienced ever!! I live in a well known estate and signed up to Afrihost. I was told that I would have a 7 day minimum / 14 day maximum wait. I work from home so I purchased a 100Gb modem to see me through. After the first week I called and asked for some sort of update and was told that the installers, Openserve, couldn't give any indication of installation. The same day I met a Openserve installer (Kis****) and he said he is in the estate daily. On day 13 I called and spoke to Kamo who told me he needed a utility bill as Openserve didn't know where the estate was. I explained that there was yet another installer on the estate who I had just spoken to. He promised to get back to me. Nothing. On day 14 I called at 8.35am and waited 15 minutes to get through to Dimpho who put me on hold for a further 55 minutes - I eventually put the cell call down at 9.45. No resolution. I fully appreciate that they may be busy, but I cannot condone the disgusting level of service and communication displayed.
