Deliver my product to another costomer

Hi, my name is Russel. I have bought a plasma stand with cash converters in boksburg through lay-bye process. I have finish paying the amount of the stand and when I went to collect the stand I was told that they have given it to another customer of which they don't know who is the customer and who delivered it to the new customer.<br> <br> I was told on Saturday that they can't deliver my stand because they don't open the storeroom on weekends I must come on Monday or during week days. I went to the shop on Monday to collect only to be told that the stand is no longer available and I must stop complaining because they will refund me my money. I was also told that they are busy with other customers and they will attend to me later. Due to frustration I end interfering with the person who was supposed to help until she push me around the shop and she final bit me. <br> <br> I have also tried to contact the head office for assistance but with no luck at all. Please help<br> <br> Regards<br> <br> Russel Mbowana<br> ***<br> [Email Removed]
