Lack of assistance from the Tax Ombudsman - SHOCKING!!!!!!

I had an issue with SARS and the tax ombudsman said they would take on my complaint. on 31 July 2020 I received an email confirming they would take on the complaint and it would take 15 working days to sort out. Those days have come and gone. Whenever I send a follow up email, I get told that they will revert back to me. Still awaiting that revert. Then SARS contacted me directly and wanted me to take a deferred payment as they would not accept the offer I was making. I called OTO to tell them this and they said I need to phone the SARS CMO and make another complaint. When I did that, they said that I already had a case with OTO and this formed part of that and OTO needed to sort it out. SARS then called me again and insisting I take the deferred payment agreement. The OTO then said they cannot help me as I am dealing with SARS directly. What does OTO expect me to do if SARS contact me directly and they are not handling the complaint like they said they would? I expected OTO to sort this out and get SARS to agree to my proposal but because they failed to do that, I am forced to fork out more monies which my company nor myself has. I am actually appalled by the lack of service from the Tax Ombudsman.
