Bad Service

I went to Woolworths Durban - West Street to exchange shoes without a till slip bought the shoes less than a month. I explained to the teller that I do not have a slip and he processed the exchanged and called for authorization. Anita came to authorize and asked where is the slip. She told me that she cannot exchange the item for me because I didn't have the slip. If it is more than R299, you have to have the slip. I told her that's new to me because I have exchanged before and was never asked for the slip. She asked me how did I pay, I told her that I used my debit card and she took it and search and was not sure what she was checking for. She asked me to go and get the statement and I did but still she searched until she approved the authorization. I waited more than 45 minutes. The service was very bad and she never explained to me what she was doing. I have never waited this long just for an exchange of the shoes, same price but different style.
