Sars is pathetic

Sars has become such a terrible place wether online or in person.i had changed my banking details in June on the mobile app...everything was ok I was notified that the changes were made thereafter I submitted my return on July 15 and was then asked to verify banking details wich I did I sent them everything they required...I was not sent any proof of communication saying they received the stuff so I called and was told my documents are there...to this Day my status remains the same on both mobile site and mobile app.wen I call the call drops....trying to get an appointment date for the walk in and next available date is late September...dear Sars why must we go thru all this is this just another way of withholding our funds
