Its impossible to have no refund.

Its highly impossible for me to get R63 WHEN I pay so much money on tax and specialy on my payslip every month,,

Based on your tax return it would appear that everything is correct due to your circumstances. You only receive a tax refund when you pay more tax than you actually owe. However it appears you are a commission earner. Did you have any expenses related to your earning commission that you keep records of, if you did then you could claim these against the commission earned.
