I would like to inquire about the warranty claim process for the 3 in 1 Stainless Rule Set that I recently purchased. There seems to be an issue with the item, and I'm hoping to get guidance on how to proceed with the claim effectively. Could you please provide me with the necessary steps I need to follow, including any required documentation or forms? Additionally, I would appreciate any information on the estimated timeline for processing such claims. Thank you for your assistance!
