Samsung sells dedected products and de***** customers

Samsung sells defected products.

I recently purchased Samsung's most expensive phone the z fold 5. I went into the pavilion(durban) branch to purchase a cover for the phone however I did not like any covers and was not going to purchase anything until the lady assisting me showed me a blue cover with the green stylist( which is R1800) . I then was intrigued and purchased it only to find out 3 days later that the stylist(pen) keeps falling out the case I went back with in seven days and they told me to come back in 5 days because they have to bring one from the gateway branch (durban), so I had to go back to the store hence its the third time going back and they swapped out the cover for another one. A few days in using the second case I had the same issue so I went back again hence the 4th time and the said they have to check with the supplier and see what's wrong, now they took over a week to get back to me just to tell me all the cases in that colour is defective and I must choice another one. I only purchased the case because of the colour, now they say they can't refund me due to there policies which is bull**** because they are de*****ing customers to purchase they defected stock and we must ship with the issue because they have want to sell defected products. Even the Manger told be on a call that all the covers are defected and I must choose another cover that I don't like if I had only know that samsung is so full of bull**** I would have just bought an iPhone 15 pro max instead of the Samsung z fold 5, only purchased this phone because I already had a iPhone but I needed another phone. This is ***** what samsung is doing. I would like feedback asap from someone higher
