Poor Service and Webpage

I orderd a Jacket online, upon clicking the purchase option i relised that i took a Medium instead of a large. I called the service dept and send a email they said that i can exchange it in store and i will recieve it within 5 -7days. Im used to Takealot great and fast service so this was a bit of a surprize. Since then 7 days has passed , called customer service 3 times and every time they said that they are escalating my problem and will call me back with a answer, no call has been made to me yet. The webpage shows that the parcel has been shipped but when i click on track it says that im lost. Poor webpage, poor service, and poor followup. Since this morning my problem is still not resoved.. Will not recommend this website to anybody
