美国采购需求：电子、照明

I've been experiencing some issues with a product I ordered through Amazon, specifically related to a switch and outlet. After a few weeks of use, I've noticed that the outlet sometimes fails to turn on, and when it does, it won't switch off without the help of a separate switch that I had to purchase. These reliability issues are concerning, and I'm looking for guidance on how to proceed with warranty service or a potential replacement. Could you please provide me with details on how to initiate a warranty claim or what steps I need to follow to resolve this situation? Any information on the replacement process would be greatly appreciated, as I'm eager to get this sorted out as soon as possible. Thank you for your assistance!
