False Adverti*****t - Item Vanishes

False adverti*****t. I was online shopping yesterday and saw a great deal on a microwave oven. I then attempted to purchase it and I realized i did not have my card on me. I got an email from Builders reminding me that I have an item in my cart which i want to pay for today and then when checking out the item vanishes, without even a reason. I then search again and then the item is nowhere on any sites of theirs. I then called the customer services and spoke with a lady named Shanell whom asked me my query and said me to send an email which I did and she said she will call me back. She never called me back and I called again and spoke with Thembella who said I will get a call in 2hrs time, but no one called, I had to call again. I then Spoke with another women who tells me that the Item I wanted is no longer available and that it takes time to come out of the website and so on. this is not my fault and this is false adverti*****t, I know the law as I practice it every day and this is not legal. All I want is the Item or a similar item for the same price or I will be going to The Advertising Standards Authority of South Africa (ASA) to lay a formal complaint. I spoke with Sbusiso the Mngr who said I will get a call within an hour, let us see now. Builders must sort out their adverti*****ts and not lie to the public like this. I am awaiting a call or I will pursue.
