After getting the completion from SARS how long does it take to be paid out?

I would like just to find out I received a letter of completion from SARS so does that mean I will get paid or what?

You should receive your refund in the next few days. If you do not, you can call SARS on 0800 007 277 to find out the reason for the delay. You may need to verify your bank details (in which case they will send you a letter) or you may have old tax returns outstanding which need to be filed.
