Foschini Alberton treating customer like ********* - Terrible customer service

Terrible service at Alberton Foschini

I bought a dress on the day of purchase the dress didn't have a tag and the cashier used another dress from the rag to scan it. The dress didn't fit and i returned it, i am now being cross questioned as if i am a ******** and why the dress doesn't have a tag. The supervisor at the store kept the dress saying that they will have to ask the cashier on the day to come explain how the purchase was done without the tag and she had the nerve to ask me why it was not annotated on the slip that the dress doesn't have a tag. I don't work there and i don't know how she expects me to know their processes

I was told to leave the dress at the store and they will decide if they will process the refund

I don't understand how are customers treated like *********

I would suggest that they watch the CCV recordings for the day of the purchase to validate that i got the dress like that hence they scanned another dress (25 September 2020 around 10:00am)
