Incorrect info

My refund paid and reversed on 4 August. I phoned the call centre and after 54 minutes, finally managed to speak to a consultant. I was advised it was reversed to validate bank details and I must send my supporting documents to *** which i did on 7 August. I was not requested to send documents before then. Today, Maria Malatsi advise me to upload them on e-filing but nowhere to upload as my bank details reflect VALID. When will my refund be processed again? I have been on the phone now for 42 minutes and number 540 in the queue. Can somebody please tell me what is really going on?
