DISAPPOINTED CUSTOMER

I purchased a pants at Woolworths in Bayside Mall, I paid R450 for it. After owning the pants for only 5 months, it completely ripped. Naturally I was very disappointed and decided to take it back. I was told that I can't get a refund or store credit for R450 as the last price it went for was R125. I was not happy with that answer so I was informed that they will send the pants away for "diagnostics" and get back to me. They then phoned me to tell me that they can't give me store credit at all as it was "wear and tear" and the pants went on the market 2 years ago. I BOUGHT IT 5 MONTHS AGO. They were insinuating that I'm a ****. I paid that price for quality and did not expect the pants to only last me a few months, if I did I would have bought any cheap pants. I'm very disappointed in Woolworths and their customer service.
