Substandard and unprofessional attitude

On 28/01/15 I bought a cover for a tablet, valued at R900. Hardly a month later I was at the store: the magnets on the cover couldn't hold and the tablet would slip out. Werner at the store told me I must leave the cover to be taken back to the supplier leaving me without a cover to protect my tablet. I refused to go without. He promised to refer the matter to the supplier and get back to me the next day but he never did. A week later I called the store and he was off, I reported the problem again, promised to be called but I was never called. About a week later I went to the store and I was referred to Julian. He told me to bring in the item for exchange. At 5 pm on 29/03/15 I was at the store with the proof of purchase. Luciano refused to exchange the product, told me the manager wasn't there and only called him at my demand. His colleague screamed at me in response to my dissatisfaction as I feel driven from pillar to post, ridiculed by these two man. None of them had name tags. I demanded to get the store manager's contact details and reluctantly gave me her name but not the last name. Luciano kept running to the office at the back. One customer exclaimed \ they are so rude"!"""
