Jack Wolfskin Thermos Safety Latch Fails, No Support from Seller

I purchased a Jack Wolfskin thermos, but the safety latch is unreliable and opens unexpectedly, posing a potential risk. I tried finding an authorized service center to address this issue, but I couldn't locate one. When I reached out to the stores that sell this brand, they informed me that they couldn't assist because my purchase was made online. This lack of support and the faulty product have left me disappointed with Jack Wolfskin. I expected better quality and customer service from such a reputable brand. I hope the company can provide a solution to this issue, as the thermos does not meet the safety standards I anticipated.
