Customer Service

I had my phone booked in a few weeks ago at Vodacom Festival Mall for repairs, access fees was paid as expected and emailed through after a few days my phone was ready for collection to my surprise some of my phone functions were disconnected and had only discovered that when I got home. I could not go to Festival Mall as I also work else where. Yesterday 21September 2020 I went back to the store to get it sorted out but I was told that the tech guy is not working and I should come back the following day even though I had explained that I just can not take day off or short day at work I have to wait for my day off as it was on the 21/09/202 . With the service I got makes it clear that they are ***********, so if a specific person is not working productivity will be on hold. I fail to understand how things are done
