Poor quality of product

I bought a hand bag from this store on the 23rd October /2021.The bag is now badly damaged. I went to return the bag on the 16th. I was told the manager was not in. Went again on the 17th she's still not in. I called her using my phone because the store telephone did not have airtime. She told me the bag is supposed to be like that. I said no ways. The treads are coming off. And now the bags has 2 colors. Which is black and yellow. The color of the bag is black. This is bad customer service. And I was supposed to return the bag not used. How was I going to see the bad is poor quality if I did not use it?
