Apple iPhone Wallet Warranty Woes

Hello, I bought an Apple wallet in January, and it has been falling off the back of my phone for the past month. When I contacted Apple customer service, they advised me to take it in for warranty evaluation. As a result, I took it to the authorized Troy dealer listed in the attached information. After inspecting the product, they claimed it was a user error, much to my dismay. The bottom part is curved, as seen in the attached video and pictures, and even the slightest touch causes it to fall off. Despite the fact that there is no damage or impact on the wallet, they insist it is a user error. When I asked under what conditions the warranty on this product applies, I received no response! This flimsy response is unworthy of a giant brand like Apple. All of my accessories are genuine Apple products that I purchase. Even the case I'm using is a genuine Apple product. I urgently request that this product be repaired. I haven't been able to use it in two weeks and would like my inconvenience to be addressed. The warranty paper and product images are enclosed. Thank you very much.
