Manager Rasslouw lusanda edgars rude towards customers

I bought Swiss backpack in Edgar's Rasslouw on the 30th of December 2022 which was R409 I only bought that pack. Now the backpack it has torn within 3months and I did explain to Lusanda The Manager that my invoice has fall into water so I have bought with my debit card I have statement from the bank she wouldn't even want to listen and keeps on saying she want the slip and not even used how can I buy backpack that they say it is strong and it has 2 year warranty but when fault arrived no one comes up with the solution of saying ok let's take it for repair until we hear from the supplier.Lusanda was even rude to me telling me I am the manager there is nothing you can do you can go to consumer protection act.I am not going to listen to you as long as you don't have an invoice because I am black I will be treated like shirt all I was wanted as a Manager I expected she will take initiative to call either supplier or Rep to explain the matter because it looks like the back pack on the stitches next to the zip it was fault but I didn't realized it till now so lusanda was full of her self and rude even is she should said to me let's send it for repair to hear what the supplier has to say and will revert back to but no because I am black she said no she can't help if the back pack has been used I think Swiss+win their back pack is not strong as they are saying it means I rather buy woolworths one as I used to but I will revert the matter to swiss+ win where they supply edgars with back packs to let them know how they treat their customers when coming to their products.ithink lusanda she needs a training for customer service because even customer doesn't have and invoice come up with the solution don't be rude to the customers that are paying your salary. And she didn't even bother to asked me did I use thank you card the only thing is an ego of saying I am a Manager how are you managing without having a good customer service to the customers edgars is not the store that has adequate management they need to take them for customer service training I wonder why they are closed
