You need to obtain a Statement of Account to the current date. You can do this via SARS eFiling or request it from the SARS Helpdesk on 0800 007277. This will show you the final tax liability/amount refundable from SARS.
From what you have told me above, it looks like the overall position is that you owe R331,72 to SARS but run an up to date Statement of Account to check.
