Exchange declined

I purchased goods from Takealot on 13 October and after some discussion my husband and I decided that we would rather want to swop the goods purchased for something else. I then logged a return for each product and then received a return ref number for the one product but a return declined for the other. I then mailed and asked why one was accepted and the other declined and both was purchased on the same day just different times I got a mail back to say thank you for bringing it to my attentin, both are declined. I missed the 30 day return by 4 days and seeing that I litteraly purchase all my stuff from Takealot, birthdays, christmas, school goodies, anniversary, etc, I would think you can go the extra mile for a client and see if the rules can be bend a bit. But after this I am done with Takealot. I will take my money and go spend it elsewhere.
