Incorrect Products advertised and delivered

I purchased a Samsung Q**** - Q-series soundbar on the 27th of January 2023. I received the order on the 7th of February 2023, however it was the incorrect order received and this was reported on the same day. We were informed within the next day that the correct soundbar was being sourced. On the 14th of Feb, we received a call stating that order was incorrectly advertised (after first informing us that it was being sourced and then a week later you tell a customer that the order was incorrectly advertised) After which the manager stated they will source the device again (which is not a guarantee) from the time of purchasing the product to the time of this product being sourced, this store is actually holding my funds for something which cannot be used and it cost more than R7000. This level of inadequate support should actually require people to be fired as it is a huge error on AVO. I expect the store to incur the loss and source this product from a 3rd party source to uphold their end of the bargain. This is a huge inconvenience to me.
