Matrix Princess Crossing - poor service and outstanding refund

Matrix Princess Crossing -Sadly on Sunday 02 February 2025 I purchased an Astrum USB 3.0 to HDMI adaptor, DA560 for R469.00. The IT person was available and unfortunately we were unable to get everything working. On Monday 02 February 2025 my friend kindly returned the item with the slip and asked for a refund as it was not suitable for my application. Her reception was abrasive and she was told that I must bring the screen and laptops in to them. She explained that this was impossible because I was working from 09:00 - 18:00. As there was no cash in the til, they took her card number and said the funds would be refunded that afternoon. When asked why they could not do a refund on the card machine she was told very assertively that the accountant did all the refunds. She left. Monday 10 February 2025 she went back to them and was told that they would phone her as soon as the money was available as there was only R400.00 in the til. So what happened to the refund to the account? In the interim, I have emailed their customer complaints and have had no response. I managed to find a number for them through a different branch and it rings no reply. Asisde from the poor service and the unpleasant attitude of the staff at this franchise, the money needs to be refunded as they have agreed to to twice. This is one business I will not use again and certainly warn people about.
