Terrible experience and customer service!

I've app**** online with my documents and proof of payment for my permanent SACE registration in August 2023. Up to now I still have no feedback. I have sent numerous emails that is left unanswered. Each time I call it's a different story and 99% of the time the person that is assisting is extremely rude. Only one person was "helpful" as she promised she will send everything through to the processing department (on 11 January 2024) because my application was never sent through... However when I followed up again on 14 February 2024 the not-so-friendly woman that assisted said I must wait another 6-8 weeks from 11 January. Now each time I call the phone just rings and the automated response that the line is unavailable comes up. Meaning this will cost me money to do yet another police clearance and certifies copies of everything to re-submit because the police clearance is only valid for 6 months. My question is: How can it take from August 2023 to March 2024 to process permanent registration and also not provide any feedback whatsoever?

Nor everyone stays close to their offices to go in and submit everything. What can one do?
