Takealot misleading people

How are they advertising products online that I don't even have stock off? Also first time buyer ordered a airfryer 7 in one 6 liter. First time parcel arrived not sealed opened and wrong item I side the box. Returned it. Got a credit ordered a week later same item advertised for R20 less in price. Quick delivery guess what they gave me again the wrong one and every time the response is out of stock. So how can they be allowed to advertise items that they don't have stock off Im still trying to understand that. Then it's my choise do I choose a credit or refund. Whom I emailed and said I would like a airfryers so why not tell. Me what is in stock and what I can choose from????? Why decide for me an say refund and guess what refund takes up to 7 days. I am traumatized with their *********** staff you can never get as far as customer service center. No manager or anyone higher up to get involve and help a or explain a situation. I have email after email with different pple that one even said a replacement was found and on its way. Soooo hope was given just to receive a SMS a refund is pending. And a sori for the inconvenience. So. Easy to type those words but knowing they messed up. Still don't know why they advertising an item that they don't have stock off???? Oooh and it's advertised agai this week but higher in price....... I heard Amazon is coming to SA. Let's hope they kick take alot out cos they misleading clients.
