Bad quality and poor customer service at Vangate mall

I purchased this school shoes for my son in April he started to wear this shoes in May and it’s September now and it’s completely broken I took to the store before the school closed and they told me it will take 2 weeks I went back to the store and they told me the shoes is still at the technologists how does that help me must my son go bare feet to school. The manager at Vangate mall completely useless and of no help. I thought Woolworths is quality but actually now
