Lovisa disappoints

I am absutely disgusted with Lovisa Jewellery Rustenburg Waterfall Mall. On Saturday 2021/10/02 I was excited to see the sale 5 for R120. So I select 5 pairs of earrings, all from the sale items, all with the red sticker that says "sale". I also select 5 rings from the tray that says R120 for 5. I select one more pair of earrings that are R50.00. I get to the till to pay and the rudest, cheekiest cashier I havd ever come across tells me some of the items I selected are not on sale because people don't put it back in the correct place. Well, excuse me, you work at Lovisa. You are supposed to put the sale items back in its place and since they all had the red sale sticker I assumed they are all on sale. So I politely ask her to cancel the transaction so that I can go select other sale items. This happened 3 times. The fourth time this cashier shouted at me " this is the last time I am helping you." I carefully select sale items and the fifth time this unprofessional cashier with no manners or etiquitte decided she is now tired of me and rang my items up. 2 items were not on the sale and she did not bother to inform me. I had a giftcard valued at R250.00. 5 Rings for R120.00 and 5 pairs of earrings for R120.00 would have worked out R240.00. Plus the pair of R50.00 earrings. My total should have been R290. So this cashier tells me the total is R390.00. Lovisa was very busy Saturday and she clearly wanted to get rid of me. So I pay R250.00 on my gift card and R140.00 on my debit card, thinking that I now have 11 items in my little bag. I get home and 2 pairs of earrings I purchased are not included. She didn't bother to give me a slip and also didn't ask for my email address to send the slip. My parcel now only included 9 items. The extra earrings I paid R 50.00 for are missing as well as a pair of earrings from the sale items. So yesterday, 2021/20/03 I went back. I tell the clearly inexperienced cashier what happened the previous day. She prints the slip of my transaction and lo and behold. One ring that was in the sale section turned out to cost R120.00 and she didn't inform me. The other item was R90.00 and also not on sale and she didn't inform me. So this second cashier came up with the great idea that I just pay for the two pairs of earrings again. What the hell???? So I told her Im not paying for it again. She phoned technical support to get the camera footage of what happened the previous day and told me to wait an hour. Needless to say I did not wait an hour. I want a full refund. Your cashiers in Rustenburg Waterfall Mall are unprofessional, rude, and a bunch of *******. I really like Lovisa's jewellery but the service is beyond poor and I fear you have lost a customer.
