Samsonite and Amazon Both Refused Responsibility for My Faulty Qibyte Backpack

I bought the Samsonite Qibyte 17.3" Anthracite Laptop Backpack (model 16N-09-006) from Amazon on 03/10/2024. Not long after I bought it, the zipper broke, making the bag completely unusable. I reached out to Amazon, but they referred me to Samsonite for assistance. When I contacted Samsonite, they stated that the bag was purchased through Amazon and advised me to reach out to them instead. I find myself caught in a frustrating situation with both companies refusing to take accountability for the defective product. I anticipated a higher level of service and a more seamless warranty process, considering the brand's reputation. I just want the faulty product fixed or exchanged. The constant back-and-forth without any resolution has been extremely frustrating. I trust this issue will be resolved swiftly.
