BAD SERVICE

I bought a bed cash on Friday at Lewis in Randburg because I was told that it was available in stock. On Monday I called the Patricia (sales lady)for the delivery and she told me that the warehouse does not have the specific bed I was looking and there is nothing she can do. She said I can add a R500 so that I can get the same brand. I am very disappointed as I do not know why she sold me the bed knowing that it is not available.
