BAD service and dishonesty from SARS!!!

I called the call canter around July'20 and and they said that there is a special stopper placed on my account....no one contacted whatsoever, then they said SARS Edenvale misplaced by documents from Portfolio dept... instead of submitting to accounts dept. I then submitted the documents online and did a follow up then they informed me of the documents are in accounts department to review the banking details with the bank etc.,I have been following up with call centre and still NO REFUND has been made to my bank account, when I called them again to found out what the problem is, they told me that it has not been rectified yet, although they received all the necessary documents and the only thing they tell me is that they can't tell me when this will be done. Waited over the "21 working day" to get this sorted and to date i am sill waiting for the 2018/19 Refund HAVE sent numerous emails / calls but i guess the only way to get to them is by putting it out there about the poor service they have been giving the tax payer.
