Takealot.com appalling after sale service after they delivered an incomplete order

Hi, I ordered and item which has a table and 2 chairs on the blue dot sale at 70% off. When it was delivered only the table was delivered - no chairs. I have been requesting for 2.5 weeks for the chairs to be delivered, and I get told that I have to return the item, I will be refunded the amount for the item, and then I can reorder the item again, except at the now non-discounted price, so I lose the discount because takealot made an error in the delivery . . . does that make sense? I have spoken to 7 different customer care people, each of which has promised to escalate the issue and request a supervisor to get back to me within 12 to 24 hours later. Well, it is now 2.5 weeks later and no communication whatsoever and no calls from any supervisor. Is this the level of after sale service you want to be known for 😟
