Bad quality of product and bad customer service and refusal to assist from the staff

I bought my son shoes a couple of months ago, he is only three and because of lockdown he hardly goes anywhere so the shows are not worn often. They started opening up in the front and it was not the first tome I experienced something like this, so I decided to take them back to the Menlyn store. The staff were not willing to assist including the manager Vivian, they said the shoes don’t have a price on the system so they can assist me if I don’t have a receipt. Now my question is Woolworths sells quality and guaranteed value for money. If that is not the case with an item a refund or exchange should be guaranteed. There should be a way for such a big chain store to access product information with or without a receipt especially for rewards members. So the staff at Menlyn were not even interested in finding an alternative, one of them who seemed to be a supervisor even had the audacity to make a remark that I should have rather gone to a Nike store. That was so shocking to hear and rather not surprising because the staff at customer service in the Menlyn branch are usually very rude. The have a bad attitude and don’t respect customers.
