Dischem's online system not aligned to store(s)?

On 8th March 2021, I made an online booking for a Covid test, selected TLC De Wiekus as the store where I planned to go for a test. At the time of the booking, there were 25 slots available at the store. I received a confirmation of the booking by SMS, with a reference number. At 15:30, I went to the store to get tested.

When I got to the store, not only did they not have my booking, they also knew nothing about the online booking system (Apparently). Seeing that they didn't have my booking, I then asked for a way to resolve the issue. I then made a booking with the nurse for 9th March, at 12:30. In the five minutes it took to resolve your bungling, I managed to upset another customer, who correctly believed that I was there to ***** her spot. See, she had an appointment, and I can understand why she got upset. In hindsight, I don't care because it was never about her.

This brings me to my issue with Dischem. Why would you have an online booking system that doesn't align with the bookings at the stores where the actual work must be done? Don't appointments normally have a date and time attached to them? Why would you omit the time, leaving it all to chance? The booking system is then a pre-booking system. You book online, then you must go to the store to make a booking – well done!

Total failure on your side. This doesn't work. Fix it. Or not. But at least I informed you that it's not working.
