Horrible service by a manager at country road

Today Sunday 20th October i went to the waterfront country road/witchery store where i had an unpleasant service from the manager Amina, the manager also made degrading comments by assuming i did not know what was the use of a make up bag. Refused to exchange items with a quality issue with proof of purchase and both items within 3 months of purchase. I am assuming this was done because i am a black woman cause i am sure she would not have done so to a white woman. My proof of purchase clearly states faulty merchandise may be returned for a refund or exchange upon presentation of your receipt, which was present for both items.
