Makro taking additional funds from my bank without consent or an order!!!!

Makro passed a double deduction on my bank account with black Friday purchasing, surely no company nor individual is allowed to deduct funds without your approval, an order or your consent? This is the same as committing ***** is it not? Then when i called them they request my personal bank statements? I will not disclose personal bank statements nor my company statements to Makro. This is so simple, they just compare the values and dates as to my details supp****, and verify the funds???? Where has the competence gone in South Africa? Can they not reconcile a simple amount they received with no order placed? The Customer Contact Centre (Awona Mshweshwe ) have been requested to contact the finance department and contact me but no response for the last 2 hours, IS THIS CUSTOMER SERVICE?????? Where does the extra funds that they deduct land up? a Xmas bonus for employees or is this another form like government control with funds?
