Takealot - appaling service!

A few months ago I ordered a desk chair for my daughter (a 3rd year university student) - it arrived on time, no problem. But it arrived without an essential ***** required to assemble the chair. I contacted takealot immediately (within an hour of receiving the chair), via email, informing them that i would like to keep the chair and requesting that they simply drop the ***** off. Failing that, i said i would go and buy the ***** myself. Long story short, takealot are not geared for that kind of service and after numerous back and forth emails (the call-line was not functioning) takealot fetched the chair. And credited me. I was not happy - though i receive a credit, my daughter was still without a desk chair. What made matters worse was the fact that when I enquired as to how long it would take to replace the chair, i was told 2-3 weeks! I asked that, surely, given the poor service, they could make an arrangement and ensure that my replacement chair arrived in a couple of days, the answer was that that was not possible. So poor service, but no attempt to make up for it! A couple of months later - unwisely, as it turns out - i decided to swallow my pride and ordered another chair for my daughter. Again, from takealot. This one arrived on Tuesday past. Again, on time. However, unbelievably, this time the chair was missing the base onto which the wheels attach! Of course, i was both incredulous as well as angry. I immediately sent an email and then found a number and spoke to an agent who was very efficient, empathetic, and friendly. She assured me that this would be sorted immediately and within an hour, i received sms notification that the faulty chair would be collected the next day. (Wednesday) Nothing, however, was said about a replacement. I emailed again. The next day came, but nothing until about 17.15 when the courier called to say he was in the area but it was too late and so would collect on the Thursday. And i received an SMS to confirm that. However, Thursday came, but the chair wasn't collected. Instead I received another SMS to say that it would be fetched today, Friday. However, I have now received an SMS informing me that it will now be collected on Monday!! And NOTHING about a replacement. Had this been the first fiasco, it would have been bad. But given that this was the second time that I was exposed to such appalling service, one would have thought that takealot would have pulled out all the stops to ensure that they tried to at least ameliorate. But nothing. Simply more delay, more poor service. Unbelievable! Jst to add: I am a very easy customer - i don't complain easily, and understand that things can go wrong. When i eventually spoke to the call agent, i was very pleasant and apolgogetic, and in fact, gave her a five star rating in the follow up survey. Because she was good. But the system clearly works against her.
