Poor Customer service

Date of Purchase was the 23/04/15. I requested an exchange due 2 the item got a major manufactured damage. I. Misplaced my slip. But my account tranaaction was picked up. The sales person refused to help me with an exchange and also refused to give me a copy of my slip. Although customer care spoke to her she still refused to help me. I am very unhappy with the service I received. I went to Edgars Chatsworth and there the staff and managers were so pleasant and they even couldn't understand why Natasha refused to help me! Edgars Chatsworth gave me a copy of my slip. But I need to contact customer care again for further assistance. I'm a customer of Edgars since 1987. I have been a loyal customer of Edgars for over 28 years and this type of Customer Service is unacceptable. This Natasha has a very bad attitude. She need more customer service training. She has no compassion watsoever. I been unemployed and just started a new job. It does not give Natasha the right not to assist me if my account is in arrears. I do have up to a six month period to exchanger an item if it as a manufactured fault. I would really appreciate it if I could simply get an exchange on shoe R460.00
