Return Policy is qualified by race

Im utterly disgusted by the treatment I received from Woolworths Canal walk customer service supervisor. I went there to do an exchange only to be told, the stock is new and needs to be audited. I will assume she imp**** the items were ******. I reffered more then 3 times to the return policy and she insisted I leave the items behind for audit. She was not even going to accommodate my traveling fair seen that I will need to go back after auditing is done. To say the least a lady working in the same department managed to get hold of me and told me a white lady was there for an exchange with new items and was gladly assisted. It's very disgusting to know that we are evaluated by color. So only whites afford a purchase as woolworths without any doubts?
