Disgusted by SARS pathetic service

The service at SARS is utterly shocking, when you owe them they are the 1st ones to demand payment but when they have to pay you there's a long waiting period story. I submitted my returns via e filling and I was die to be refunded on the 09/07/2017,the refund was reversed due to when I uploaded my banking details on the system my initials we incorrect which I take responsibility, and I called them and they said I needed to upload all my details again from ID to bank statements which I did on the 27 July and I was told the verification will take 21 days for them to uplift the bank stopper I waited patiently for the 21 days and still the bank stopper has not been uplifted and still my refund is sitting with them evrytime I call the consultants will tell me that the case still being investigated but they did confirm that they got the documents and they valid so what's the hold up, on the 2nd of Sep o decided to complain via their complaints department and again I'm told that the case is still being investigated and it might take 21 days for them to finalise so now it means for you to get a refund from Sars so you have to wait 42 days to be refunded I don't understand the system.
