Don't buy Woolworths Walkmates

I purchased a pair of girls walkmates school shoes over 6 months ago and have to say that I am extremely disappointed in the quality and feedback I got from Woolworths. A piece of the heel broke off of the shoe. The rest of the shoe quality is in perfect condition as you could see it wasn't abused. Woolworths policy said as its over 6 months they can't refund and its normal wear and tear. My question to them is how does the middle of the shoe just break off. The quality of there product has dropped that I would advise clients to steer away or return within 6 months because they really don't care anymore. I have to say that I am extremely disappointed in the walkmates products
