Poor SARS response to branch bookings

I needed to reregister my ID since SARS made a mistake on my 2022 tax return and gave me an old ID number. I therefore needed to make an appointment at a SARS branch. I sent the SMS for the booking - got a return SMS they would 'get back to me within 3 working days' but it's been 6 working days and still waiting. I contacted by phone at 8am, waited in the queue for 1 hour and 46 minutes, and when I was nr 2 in the queue they cut me off. Truly terrible service!
