Woolworths, poor service, bad quality!!!!!!!!!!!

Early January, this year, I bought my daughters school shoes( walk mates) at Woolworths. I was told to keep my proof of payment slip, because it is valid for up to 6 months guaranteed. I opted to buy Walk mates, because they advertised as high quality shoes. Its been 4 months now, and the soles of the shoes are worn. I called the Woolworths costumer care office and they advised me to exchange shoes at nearest branch. I took the shoes back, as this was not the quality I expected from Woolworths, they definitely down rated in their quality, not to mention their poor client service. The manager told me they have to send the shoes away, to test why it's worn. What must my child wear to school in the meantime? And why promise a guarantee on walk mates if it's not true. The manager kept raising his voice and showing me the board with their 3 months return policy. Yes,, I know that. But what about the six months return policy, if one have valid proof of payment and item is disappointedly not such a good quality as promised. Woolworths was always, again, I state,, was, my go to shop, but no more. The money paid for poor service, bad quality and broken promises is just not worth it.
