Netstar does not want my business.

Poor Poor Service. It is like they do not want my business. I have been struggling since mid February 2020 to get Netstar to do an installation. I have made appointments, they are always hours late, that I need to cancel. When I make new appointments, they say they will phone me back to confirm location and time. They never phone me back, so I phone them to phone me to try and get them to call me. They never call back. It is absurd the amount of phone calls and airtime I have wasted trying to get an installation out of them. I get that it is Lock down but this has been a month and a half before anyone even mentioned the word Lock down in South Africa. Could anyone suggest a better alternative that works in association with Outsurance that I could consider, since Netstar does not want my business.
