Samsung Clearwater screenprotectors for S10E product is faulty! Not happy

I bought a Samsung s10 E IN April and I bought the screen protector. I then submitted a complaint on Hello Peter as the screen protector had a hairline crack whilst I was typing. Denver the manager called me and said that I can come to the store and replace the screen protector which I did within 5 days, the new screen protector had a hairline crack again. I called Denver back and he said that I can come in to have it replaced, so this past Saturday I replaced the screen protector the 25th and today the 29th....Guess what the screen protector has a crack. I asked Denver if it could be a bad batch and he said that they sold so many and no other customer complained! So what is he insinuating that I have been damaging the screen protector? He assessed the screen cover and said that the phone was dropped which is not true as I am guarding the phone with my life. It was a birthday present and I am very careful with my phone. 3 screen protectors in a space of one and a half month. It lasts +- 5 days! Can this be my fault. I do not keep my phone in my handbag. I am so utterly discussed with this product. R600 might not be a lot of money to many but you pay for quality and that is why I bought the screen protector. Clearly there is something wrong with the product. Maybe other customers do not want to complaint. Please do not generalize and attend to each complaint on it's own merit. I really would like to hear what Denver or anyone from the branch has to say.
