Got the same mail last week. i have been into the link and its as usual all about SARS, nowhere does it ask how pleased we are about the veification process timeframe, and the inability to confirm refunds due.
Filed on the 2nd July, uploaded supporting documents on 2nd July, recieved confirmation of receipt of supporting docs on 2nd July. SARS status = Return Assesed...................still no completion letter. dont even try and contact SARS, your waiting period is 10 minutes, call back option also...
