Takealot sending incorrect order

I am a regular Takealot shopper and I have never experienced bad service, up to now! I am totally frustrated - on 25 October 2021 I ordered and paid for a stroller for my baby, when it arrived, it was totally damaged, the box, the footrest was bent and the one clip on the side was completely broken in half. I submitted the return to Takealot on 27.10.2021 to please exchange, their feedback was that the item is now out of stock and they can only credit my Takealot account - fair enough - then I ordered another one on 01.11.2021 - paid with my credit and EFT the R151 that was short. The item got delivered at my workplace while I was on leave and I got in on Monday 08.11.2021 - just to get home to a total different stroller than the one I have ordered - it does not even look alike and I cannot find it on Takealot's website either. That same afternoon I submitted the return and just before 4pm I dropped the stroller off at the Bethlehem Pick up point for a return / exchange, just to get feedback that day that the 2nd one I have ordered is now also out of stock?? Up to date I am still waiting on my refund - whenever I mail Takealot the only answer I get is that whenever my order arrives at their warehouse, it will be investigated - after I even sent them photos of my order and of the stroller received. The reason for ordering was that I NEED it for my baby, now I am sitting without any wheels for my baby since 25 October!!! (I sold her old big pram). If it was an error or negligence on my side I would not mind the investigation and this taking this long - but this was not my error - if an item is out of stock, why do they still advertise it on their website??? Why take so long if it straight forward that the error was not on the client's side.
