Unacceptable customer service

I have called Wimpy Mdantsane mall to ask for assistance retrieving details of a missing slip that I do not remember receiving when I went to buy from their store. I have all the details needed, the card number, date , time and order details. I have explained to Nobuntu ( not 100% sure if I got this name correct)that I have used a corporate credit card which requires me to submit slips on a monthly basis.

Her response was the store doesn't pull previous slips which I disagreed with her as I'm also coming from retail background. I have proceeded and asked for a manager and I was told she's off duty and she doesn't know what time the second incharge would come in.

I find the employee *********** to deal with customers. Unteachable aswel, I gave her tips on how to handle customer queries. She didn't offer to take my details and find out how they can assist me, instead she argued with me because I have retail background and I know these things. She ended with a very distaful customer service..dropping the call on my ear twice.

This is the most disgusting customer service I have ever received in my entire life. This kind of service is disappointing particularly in a black customer area. Is this how the customers are treated there ? I have been to all the Wimpy stores on a weekly basis and this is shocking.
