beware of possible scam see below on refund process http://www.sars.gov.za/AllDocs/Documents/MediaReleases/2009/SARS-MR-2009-007%20-%20Media%20release%20on%20SARS%20cautions%20taxpayers%20on%20fraud%20scams%20-%209%20February%202009.pdf
If a refund is due to the taxpayer SARS automatically pays the refund into the taxpayer's bank account; provided that the details are correct. If banking details are not correct the taxpayer must visit a SARS branch office with supporting documents to correct the bank account details. To prevent fraud, SARS last year did away with issuing of refund cheques and will only pay refunds into verified bank accounts. In this regard SARS has contacted approximately 150 000 taxpayers whose bank account details were not provided on their income tax return or who bank account details could not be verified to request that they correct these to receive refunds due. To prevent fraud or "phishing", these taxpayers are required to correct their details in person at a SARS branch. The SARS Anti-Corruption an Fraud Hotline is 0800 002870
