Stanley Thermos Stops Keeping Drinks Hot or Cold and Starts Leaking

I purchased a Stanley thermos, and after some time, it began failing to keep both hot and cold beverages at the proper temperature. In addition, the thermos was leaking from the button area on the lid. Because of these issues, I sent the thermos to the service center for inspection.

After inspecting the product, the service center stated that there was no consumer-related damage or misuse. Despite this, they did not replace the product and instead said they wanted to inspect it again. I specifically told them that I was requesting a replacement, but they asked to conduct a second inspection, which I agreed to. However, after the second inspection, the product was simply shipped back to me without any notification, explanation, inspection report, or message being provided.

I have been dealing with this issue for approximately a week, and I still have not been given any concrete information about the cause of the problem or any actual solution. Regarding support request number 69636-87616, I request that the thermos be evaluated as a defective product and replaced with a new one, or that another appropriate solution be provided.
