Never will I ever

I am extremely unhappy with takealot... Bought a smart watch and it got delivered..only to find out its not compatible with my phone, I request for an exchange, driver collected it and I never heard from them again. I escalated the matter and Carmen Jansen responded and created another return to be dropped off, how do I drop off a package that's been collected already??? I then send her an email and she hasn't bothered in responding.. I'm so mad and irritated by them.
