DD i get dis treatment because I'm black..

I bought a deep fryer on the 28 of July at springs cash converters, i took it back bcoz it only worked once on the 8 of August so the manager Laetitia Steel told me rudely told me that she can't give me my money back because they have to take the deep fry for repairs . when i tried to explain that dis is an old version so I'm concerned dat it might not be permanently fixed n that the return policy was not explained to me n it's not on De slip she said it's not her problem as she is not the one who sold it to me n she is not there to teach me how to read after i left she took the deep fryer and threw it outside the store... So i went back to the store coz i realize she ddnt giv me the return slip... When i got there i found it outside.. i asked her n she gave me attitude .. so the sale man took it in the store n gave me the slip... I'm so disappointed i have been buy there a lot of things ... wat is Gona happen am i Gona take De deep fryer that was thrown outside???
