SARS - Special Stopper - Pathetic Service

I submitted my tax return via e-filing on the 11th of July and received my ITA34 immediately with a refund due to me, I called the call centre after 4 days to find out when I will receive my refund, I was told to be patient. I called again after a few days only to be told I need to go to a SARS branch to confirm my banking details and provide supporting documentation. I went to SARS in Bellville and after waiting 3 hours in a quee I was told there was a special stopper on my account. I did not receive any communication and when I check my details on e-filing, everything is showing as verified, so if I did not call I wouldn't have known and only the second time I called I was even told to verify my details. Again a few days pass and I call once again only to be told that the are no turn around times for removing the special stopper and I need to be patient. How can they not have a time estimate, so is it going to take 1 week, 3 months? This is really pathetic as they are so quick to hound you when you owe them money but when the tables are turned they don't want to pay MY money back to me. This is really very poor service and unacceptable, at least tell me how long I am going to have to wait.
