Legit Parow Centre's Service is a disgrace. I AM NOT A DOG!

In Friday I rushed into legit 5 minutes before closing time to buy those 2 for R300 dresses(size 4). I did not fit them on due to time constraints but I told the sales assistant I would return it if it doesn't fit.. Unfortunately, it did not fit (even tho I generally wear a size 4). I go to Legit to exchange it obvious for a bigger size only to find there's only a bigger size in the 1 dress and no other size 6 in the other dress or any other promo dress that I liked. I obviously couldn't take just 1 dress so I asked for my cash back to try to purchase the dresses at another store. The cashier was extremely rude. I'm a regular customer but the way I was treated today I'll never go back. She has a gold L in her teeth, is tall and has big hips. Firstly she asked loudly what's your reason for refund in a ugly attitude, I took a minute in shock at her tone then said I'm not finding anything suitable here. Then she says 'well here's plenty of different dresses in different sizes here' in the most snarkish way possible even tho I said NON IS SUITABLE FOR Me she asks for my details and throws the pen. At that moment I tell her there's no need for her to treat me like I'm a dog she's like 'excuse me in a threatening tone' I said nvm. She types my name wrong I correct her nicely she's like 'whatever'. I'm so disgusted at this behavior. So so disgusted. Know that I'm a government employee and earn a very good salary which a large portion goes shopping at legit but after today no no I'm sorry. A word of advise to the managers of legit is that your sales this festive period is not going to be good if your employees are like this. This girl should be rebuked. I asked her for her name she just kept quiet.
