Ackerman's Clearwater Want the Customer Pay For the Cost of their staff member.

I went to Ackerman's Clearwater Mall on the 23rd October 2021. I made 2 purchases. When we were leaving the store the beeper went off. Upon checking my packages, they realized that two of the items in the packets had security tags on them that the cashier neglected to remove.

Today the 25th October 2021, I went through the slips because something just didn't add up. I realized that the cashier charged one of the items twice on the slip.

When I called Ackerman's Clearwater they said I need to come to the store so they can refund my Credit Card that I had used to purchase.

I don't understand why I am expected to drive and spend R150 worth of petrol to perform a refund of R160. This feels like I need to pay for someone else's mistake.

To top it off, they say the email address used in the store, does not accept external emails, so they lady in charge of the store today suggested I send a WhatsApp message. How is that even an option.

They want to handle a business dispute via a personal WhatsApp number?

Why am I the one expected to carry the cost of the mistake of an Ackerman's staff member????
