Being cheated out of R480 deposit

I first lay bye a cupboard in 2016 at fair price in Jouberton, one day when I wanted to go and pay the shop moved. So I went to the one in town and they said they could help me and they did. So I asked them instead of the cupboard I would like the fridge their system was just not working with me. So I was told to cancel and make a new lay bye which I did to my surprise today I was told I canceled and received the money there is nothing they can do. So I bought the fridge cash and left - on the 23rd on March I did sign to cancel so that I can make a new lay buy because the dam system was not working on my favor. They called me and says that my new card is ready, i work in zeerust so i come home to be told that i took the money. I have a receipt that says on the 29th March 2023 new lay bye deposit R480!! Thats a lot of money just to let it slide and forget about it. I am not happy even the lady that helped with the fridge made a joke saying let me explain everything before you sign because tomorrow I'm getting my fridge. I just come from the doctor I had an operation 2 weeks ago so I wasn't I the mood to fight. I was going to leave it alone but Now I'm at home sitting looking at this receipt and I'm boiling the sales person that helped me on that day was kamogelo funeka. Fair price were is my money that's a lot if money I want it back. I will never go and buy there anymore you guys were aware the system was just kicking me out so now you'll keep my money BAD BAD BAD
