Poor service from Maxidor

Enquired on 16/11/2022 to attend to the moving of an existing Maxidor as we are remodelling the house and confirmed our appointment at the property and obtain quote on 18/11/2022 from Martin Landman. On quote it was stated 10-15 working days lead time. Payment for work was done on 23/11/2022. Installation appointment was scheduled for Saterday 10/12/2022. At arrival of a Chris to do the installation he indicate that he will not be able to do the work. After already complaining with the admin clerk Lize-Mari about the issue that the installation is not done as this is to move an existing gate, there cannot be much to be produced. Called back Martin Landman to state the message from the installer Chris that will not be able to do the work and made it clear my son is now unsafe as his new room will not be behind the safety gate. I wanted to talk to the owner of Maxidor SA and he inside he is the owner and drop the call. This is unpleasant if you have a long lead time after you paid for a service / product, then they did not do the measurement correctly at quoting, could not install 3 weeks later and then have a bad attitude.
