Jaymees Midas ****med me R375

I ordered a clutch kit at Jaymees Midas and the agreement was that it was gonna arrive the next day before 10. I went to the store at 11 and the kit was not there. I asked for a refund and they kept on refusing and I was not willing to leave without my money because I did not get the product. They started ganging up on me saying I won't get my money. They decided to charge me for handling fee for a product that I did not receive and it was not in store when I got there. So instead of receiving a full refund of R2500 that I initially paid. They game me R2125. That means Midas ****med me R375. I want my money back.
