BAD BAD BAD SERVICE - Telling a paying customer you are waisting their time

BAD BAD BAD. If I could give no stars, I would. I have been trying for, Telkom and Openserve to relocate my fibre to my new home. Many phone calls later they said they would come and do the installation on the 27th February 2024. As I am working full time I had to arrange for someone to be at the home. They NEVER showed. When I phoned all they could say, they know nothing about it. So I received an message on the 28th February 2024 to book a time slot and for them to come and do the installation. I made the booking for the 29th February 2024 between 08:00 and 10:00, again making arrangements for someone to be at the home. I received a message were you can track the technician, on the app it showed the technician was at my home at 07:49. Waited and nobody came to the door, tried to phone him five times, every time he ends the call. Phoned Openserve at 08:56 and all they can say is you need to phone sales at Telkom. I said, I did and they refer me to you and now you are referring me back to them. NO HELP AT ALL. I finally get hold of the technician at 09:06, he sounds like he was sleeping, I ask him, what time he will be at my house, he replies at 10:30, I said to him what is the use of making a booking if he is late and the person I arrange to wait for him also needs to get to work. His reply YOU ARE WASTING MY TIME NOW!!!!!!!! What bad service to tell a paying customer that has been a loyal paying customer for years that you are wasting his time, seeing they do not give any support or service and are late!!!!!!
