********* Practice : Selling item to a different client that has already been paid for

I purchased a dresser on the 06/03/2021 at Deco furn Silverlakes at 11:02. Paid for the items and proceed to load my car. The dresser did not fit so I informed them that I would return around 14:00 to collect. When I returned I was left to wait for 45mins only to be called by the "Store manager" Ranga and be informed that the item I bought and paid for we sold for a 2nd time and the client was told to immediately take it as I was due to return. The manager then proceed to say he will source an alternative. I asked why could I then not have the one on display to which he indicated is not allowed. He returned another 20mins later and told me he sourced one in CPT which will be in PTA by Friday. I requested it to be delivered and the condition of the item to be suitable. He promised to call me on the 7/3 to give me an update. That did not happen. At 11:20 I called the Deco furn call centre spoke to Cherrie who transferred me to Sharkira who then transferred me to the northriding store who then got the Regional manager office to call me. Naomi called for context and let me know the regional manager will call me. This did not happen instead JP from the silverlakes store who is also the store manager called and said they don't have any items in the entire SA and the items on display as per the regional manager cannot be sold. So I asked if the whole of SA does not have stock why does the display matter? JP then indicated that this is the case and I should kindly collect my refund or it can be sent to me if I complete a form. Mr Cornel who is apparently the regional manager is not willing to correct this or speak to me. This is so ********* - the dresser was knowingly sold for a 2nd time and provided to a client whilst a sold sticker was on the item and no effort to resolve this matter has been made by Deco furn
