Sars and ABSA Bank review: Pls refund my money

Good Day

Today the 24th of May 2022 SARS debited R18.500 from my Absa account without my knowledge.. I am divorced and been trying to make ends meet.. I have 3 kids to support.. My ex husband and I have been divorced the islamic way...10years to date.. How can SARS do this.. I buy and sell small items to earn a living.. how can I get my money back.. I'm in tears.. The money was to be paid to my suppliers.. I'm left with R500
