Zara's pathetic service and quality concern.

I bought a shoe on Friday 27 July 2018 at 19:21.I was satisfied with how the shoe fit.This very shoe had scratches at the sole but I did not let the cashier know nor did she check.Saturday evening as I was planning to wear the shoe it felt very uncomfortable and I realised the quality is **** and proves to be painful on my feet so I removed them immediately planning on returning them. Sunday evening a cashier at Zara V&A kids section assisted with an attitude an annoyance telling me that she will not take the shoes as they have been worn.I then take time to explain what happened and she refused to listen to me continuing to talk while I was talking.She calls her manager who then calls another manager saying they will not take the shoes as policy does not allow.I then ask them what happens when you buy the shoe in that condition and no one bothered to explain that you will not be able to return the shoe.Its upsetting to purchase something that will clearly have repercussions of this nature.My case has not been resolved and I left the store in annoyance.Zara SA apparell quality is whack and their service is pathetic.
