Why should I pay for SARS' incompetence?

Have a company registered since 2015 but has never done any business. I keep receiving emails about a penalty and every time I call the call centre I am unable to go through. I have tried to do the efiling myself but just can't seem to get it right. I cannot afford to hire someone to do it for me since the business isn't trading. The penalties keep growing meanwhile I cannot get through to the call centre. No walk ins allowed at a branch. I am frustrated and angry because how will I be able to pay the penalty if it keeps growing every month. I even feel like deregistering my company just because of our useless SARS contact centre. They have a callback option which I always choose but they have never called me back. I am writing this now after receiving yet another email at 01:50 am.
