Appalling Service - Have to wait 3 weeks for feedback, got cut off twice

I submitted my original assessment and then got feedback from SARS. I then disputed it and I included business km as I do get a car allowance - 1st call to the call centre of SARS. I give them my RSA ID, they say I am not registered as a Tax person (Although I can give them the tax number). Got cut off. Made next call, person told me that the IRP5 submitted by my Company is not mine at all. It is just weird that the yearly salary and name and surname matches. I get the idea they do not really know what they are looking at or for, In the background you could here people talking crazily, really not a place to conduct professional conversations on the phone - I would like to know what the status of my TAX return is - please refer to case number *** please. They say it will take 21 days to answer me. I am also in a service orientated industry and if I tell my clients to wait 3 weeks I will lose all my clients - I am desperate for some DECENT and professional assistance please. please Proof me wrong that there is indeed someone out there in SARS who cares
