Shocking fibre service from VODACOM!

I live in Port Elizabeth but relocating to Johannesburg in a couple of weeks. Because I use the internet daily for my business, I decided to sign a lease on a Johannesburg house a few weeks ahead of my actual relocation, so that my fibre would be installed ahead of me getting there. My daughter insisted on using Vodacom as the service provider, even though I was quite happy with my current Telkom service... ..contacted them weeks ago and the installation was scheduled for TODAY, 16 September 2019, between 9 am and 1 pm. She took a day off work ESPECIALLY to be at the empty house and await the technicians. She was there at 8:30 am and now at 6:40 pm, she is still waiting...and in tears. They just didn't bother to pitch!! Or let her know that they weren't coming!!! Is this how new VODACOM customers are treated? We are furious and very disappointed. All that we can get out of them after phoning or tweeting, is a PATHETIC, GENERICresponse, "We will look into this for you" Which year will that be???
