Terrible Service from Takealot

I am so disappointed in Takealot. They make such a big thing about their Service and new pickup/drop-off points yet are terrible with their Service. I ordered an Item from them 10 days ago and received it after 2 days. To my surprise, they sent me the incorrect item so logged a return with them. I then decided to drive to their Rivonia Takealot drop-off office so that it could be taken back and send me the correct Item I paid for. I was told that the item needs to first be sent to the warehouse, checked and then they can send the correct item or refund me the money. Now 7 days have gone by and still the only feedback I get is that they still waiting for it to get to the Warehouse? All the agents can reply is that they cannot do anything until it is back in the warehouse... Really!!! I dropped it off at your premises!! How can it take 7 days plus to get from YOUR premises to YOUR Warehouse??? You are quick at taking my money and you still have my Item. YOU made the mistake and it is your responsibility to make ammends to this. Your Service, on this occasion is SHOCKING!!! I am still waiting.
