Very bad customer service

On the Thursday before Easter I went to the store and was told they do not have an item I was looking for as it was on promotion but the store had not received it. I went again on Tuesday the 07.04.2014, and I spoke to Kevin who promised that he will order the item at Phalaborwa and I asked him why so far when the branch in town shows that they 4units of the Odessa tv stand. He said they are unsaleable. I didn't believe him but I kept quiet.he promised I will get the item tomorrow morning. Upto Friday he had not contacted me.i went again on the 14.04 and he promised again that I will get same day at 16:00 then I paid for the stand. The consultant who was writing on the customer document told Kevin that he shouldn't sell something that is not on stock but he promised that the item is coming as he has sent someone to fetch it at Phalaborwa. Today I went to the store and he was not there. I was helped by Jimmy who contacted the store in town and was told that they are sold out. My brother went into the store 5minutes after that and a guy called Mojapelo told him the stock is in the stockroom and he can sell it to him. I called Jim and told him that that, but stil the store told him no
