No customer service/ customer recovery

I booked online for Covid 19 vaccination for my daughter at 1030am, 11 July 2022. We got there and weren’t attended to for about 10mins. After our forms were taken we were told people with clinic appointments have priority over us who made covid 19 vaccination, the sister blatantly told me it’s a techie error with no apology and dismissed me saying she will see us after the clinic appointment. If this is the case, how come customers aren’t advised online or in the pharmacy with placards so that I don’t have to take time off work and to be told this excuse... secondly I booked for Covid 19 online and was told I didn’t register for the vaccine instead for a clinic consultation for 1030am and there was someone else with the same appointment.... totally no customer service or customer recovery whatsoever. Totally disappointing
