Poor service

I'm so disappointed in the service of Takealot. After being such a loyal customer for so long I feel I was mistreated. Ordered a sneaker for my husband, he fitted 1 shoe and it was too tight. Immediately I returned it and they told me the shoe was used they can't accept it. Exactly how are you to know something doesn't fit you unless you try it. I'm never using this app again, even deleted it!
