Disgusting after sale service

I signed up for the Fibre connection on the 12th December and was told that within 48hours the installation team will contact me to schedule installation date. Followed up after the 48hours passed and got a ticket ref ISP-***. Got a call from the installation team and scheduled appointment for Friday 15th December. "Fly.cool: Hi Abongile Your Installation is set for 2023-12-15 08:30:00 . Please arrange a responsible person to be available" I waited whole day on Friday, send messages and no response, on the 16th December got another ticket ref ISP-*** and that was the last time I got response from Fly Cool. It's the 19th December 2023 and no one has responded, I've been sending messages daily with no response back. Sad thing is I need the installation and Fibre ASAP for work and I already paid R500 for everything and yet nothing. I am disgusted that Fly Cool request we pay for subscription firsts and yet they don't do what they promised. I am beyond ****ed, I need my installation done ASAP and need my connection activated, can someone call me today to sort this out.
