Bad service and low quality shoes.

I bought school shoes for my son in February at Woolworths, in July I saw my son coming back with socks wet even though he was wearing shoes. When I checked the shoes the bottom was damaged so in the second week I took them back. They told me they will take them for quality check which took 5 weeks and they said the results was unjustified, meaning I let the child wear the shoe even though it was damaged. How in my right mind would I do that to my child. I am so disappointed that I bought a shoe and it does not even last a year.
