Unrealiable Installers hired by multichoice

I received a call from a sales agent on the 29/04/2024 regarding an Ultra Price lock. I was vetted and I qualified. I was asked when would I like the decoder to be installed, I advised that on the 02/05/2024 I will be available. All details were confirmed and an installer was assigned. The name of the installer is Glass Dudez Accreditation number: ***9MC Contact: ***. These installers confirmed an installation that didn't happen on the 01/05/2024, When I called to check with Multichoice Ntobeko advised that number has changed on his side in terms of the package. I waited for the installer on the 02/05/2024 as per the scheduled date and time 09:00 am. Upon waiting I received an sms at 09:18am indicating that I am not available and the installation will be rescheduled for 04/05/2024 before 5pm. I called the call centre to find out what buffoonery was that, I was given another installer in Welkom mind you i am in Stretford, I called again and was given Ndlhovu Satellite Installations in Ext2 Orange Farm *** number rungs forever. I need to know if you vet your installers or before assigning any jobs to them do you call and verify. Because now I am losing two days of not going to work waiting for nothing. Why is it that your installers can lie about contacting a person who set the time themselves. And also do you check and update your installers details or you are just happy to keep customers? I called now and the lady took her own time trying to get hold of these two installers to no avail. the matter escalated and I hope they will be dealt with ***. I failed to honor a payment because I am waiting for a new subscription to be activated and I can pay. Now I can't watch TV.
