Very disappointed!!

Absolutely terrible. I placed 3 orders of which there is a problem with all of them. I order a phone at a discounted price asking for delivery the saturday. Then the estimated delivery is 2 weeks later on a Tuesday. Then i get a notification it is delayed with another week. We called them to find out whats going on to find out theres no stock in the warehouse. Why then have it on the site if you dont have stock? Then i place 2 orders for set of pots on a 83% discounted price. Paid and delivery within 2 weeks. Several hours later i get a notification that i will be refunded because the price is wrong. Seriously what is going on with takealot?
