Appalling customer service

Horrible horrible experience. I ordered a wardrobe for my toddlers new bedroom. We planned to introduce him to his bedroom on the weekend after the takealot delivery was scheduled. Takealot charged me R200 for a large item delivery and what got delivered to me was a small box weighing not even 1kg. How can someone at the warehouse think that this little box is a "wardrobe" and send it to me in a big bakkie delivering oversized packages!! I wrote to them on the help channel and receive a response much much later. Then radio silence till i found the number and chased up the customer service agent. Again, no response till i call again and they have the audacity to tell me that the warehouse has confirmed they *****ed up but no one has had the time to relay the message to me. Then they said i will need to first return the incorrect product and then wait till they can deliver the product to me again. They promised to colelct the product within the hour and then i receive an email (today is Frida) that they will only collect on Monday. I chased up customer service again and they said they will look into it ... radio silence again ... and now at 18:20 they email me saying that the drivers are booked and so Monday it is. I cannot understand why they then cannot send the correct product on Monday (since the warehouse has acknowledged that they *****ed up the delivery) and take back the incorrect product? Or organise a special delivery to make up for their mistake?? This mess up comes after the last few orders had to be returned due to substandard/defective products. Takealot is not what it used to be and I am moving my business to smaller businesses who care about their customers.
