I bought a shoe that was damaged the following day and I received a bad attitude and unsatisfactory treatment when I return the shoe

I bought a black slingback shoe at Truworths in Umtata, BT Ngebs Mall. I bought this shoe on the 11th February (Sunday), then on Monday I put on my shoe to work, around 10 am when I was on my way to a meeting I heard noise when I am walking then when I check my shoes, I discovered that I lost 1 tip. I felt so embarrassed walking around with a noisy shoe, but I had no choice because I did not have another pair of shoes. I walked around with that shoe till the end of business. I went home to change the shoes, then I went back to the store. I asked for an exchange or a refund, the lady at the till called her manager. The manager said they will take the shoe to their head office in Cape Town for Quality Assurance and I I will get feedback after 2 weeks. I said what should I do in this 2 weeks because I bought this shoe so that I can wear it at work, should I buy a new shoe whilst you busy with your quality assurance? You can see that I bought this shoe here yesterday, here is my receipt and now you tell me about 2 weeks. She said it is up to me to buy or not buy another shoe, because this matter is beyond her store and these shoes they come with extra tips, so I should have replaced the tip instead of walking with the shoe without tips. I asked her if I was supposed to carry tips everywhere I go, she said those tips are put in that box for that purpose. When I bought the shoes, nobody told me that I should carry the tips everywhere I go and nobody taught me to replace tips as I am not a shoe mechanic. I told her that if they were transparent enough I could have never spent my R420 on a shoe that I need to carry tip from day 1. So I am still waiting for the feedback in 2 weeks time, this is annoying me.
