Poor service delivery

On Sunday, 22-11-2019 just after 9 am I went to buy 4 globes for a chandelier that I have purchased the week before, at the same store. I wens to pay and the cashier, Curtis, said he could not give me a receipt for my cash purchase, he said he had a problem with his printer. Once if got home, I discovered it was the wrong globes. On Tuesday if phoned the store I eventually spoke to the manager, Shaanaz Arendse. She informed me that she could not find any movement on their system, on the date that I have purchased the globes and that they therefor can not exchange or refund me, as I don't have any prove of purchase, insinuating that I have ****** the globes. She was not helpful at all, and very rude. Tuesday afternoon, after work, I went to the same store, after they have spoken to my husband and said I could come and exchange it. Shop staff went trough the stock in the shop and then found that the globes was never sold through the system, which make me wonder if it was ever ringed up, which coursed me unnecessary embarrassment, and inconveniences, no apology was given and store manager was conveniently locked in her office. It was a very embarrassing experience for me.
