Mr Price Group / MRP review: careless cashier

Good day
On Sunday, 26th January 2019 11.01am I purchased a hand bag and white vest t-shirt from mr. Price Cleary park. I was asked to give my email for my receipt like always. My shopping bag was checked by security and it was cleared. To my surprise when i got to the car outside the mall when i checked my shopping bag i noticed that an item(the white vest) was missing from my shopping bag. I went back to the store and showed the security the smal slip that was given that showed i purchased 2 items and told her that there's an item missing from my bag. The security went to the cashier and required about it and all she said was "oh it must be this vest"that was laying one side on the counter and just gave it without any apology or remorse. Few minutes ago when i checked my email for the receipt it shows that i never received it but i gave them the correct email adress. I find this unacceptable that the cashiers has no customer skills or is just poorly trained. I wil never shop at Mr. Price cleary park again seeing that I've never received this kind of bad service at mr. Price Greenacers. She was clearly having a bad day and her head was not at work.. Who knows what her other customers had to deal with today because she was careless.
I have the following details i can give u that i received on the small receipt
