TAKEALOT WASTING MY TIME!!!

I have ordered many items at Takealot, all my textbooks, our dog food monthly and replacement cellphones for my office. I have tried to purchase an iPhone 6S plus but everytime (just after payment is made), they tell me there is no stock! Surely there is a law against using bait items to get a sale? So after losing one item at R15 999 for a 128gb, they offer me a credit, we choose a 64gb for more at R16 999 and while I am facilitating the payment of the R1000, I try be proactive if the product is in stock as I do not have time for this, the lady tells me she will check and come back to me in 30 minutes, that's almost an hour ago!!!! And I don't get a reference email like I did when I called the last time so can't even query. There is another place offering the device at the amount I wanted and now my money is tied up at Takealot. Please don't come with your 3rd party Ts & Cs, I bought it from your app and paid the money into your account! I will never buy from your company ever again if this is how you do business. Even if I go into a store, if the item is not available, they still honour the price it was advertised at with a rain cheque.
