Manager require people skills

I would like to request Makro to send Andre (head of security) from Germiston to a Soft / People skills training. He really needs some training on how to approach and handle customers. On the 22nd of October around 2:30pm Me, my hubby and some family members went to makro to buy alcohol. The total amount for alcohol was around R15000, my hubby gave the cashier his card and it declined twice. (Reason he forgot to increase the purchasing amount before we went to Makro ). I then gave the cashier my card to debit from it but the cashier took my card and send it to security instead of my husband. With all the cyber crime happening I am not comfortable to leave my bank card with strangers. Definitely if someone use my card to purchase online I will definitely suspect Makro because that's the only time that they took my card without my present. After waiting for almost half an hour Andre came without even apologizing for inconveniencing us and requested to see my ID. I then told him that the cashier mixed the debit cards. I understand that people ***** other peoples card but the manner in which he approached us was not in a professional way.
