Skechers Refused to Replace My Son's Light-Up Shoes Despite Both Lights Failing

On September 8, 2024, I purchased a pair of light-up shoes for my son from Skechers. Approximately 1.5 months later, the lights on both shoes suddenly stopped working. I submitted the shoes to the store for inspection, and I received a message stating that the shoes had been examined and that there was no manufacturing defect. However, I question what non-manufacturing issue could possibly cause the lights on both shoes to stop functioning simultaneously. When I visited the store to collect the shoes and expressed my dissatisfaction, I was advised to send the shoes for inspection again, as “perhaps a different outcome might result.” Following this suggestion, I resubmitted the shoes for inspection on Monday, December 2, 2024. On Saturday, December 7, 2024, I received the same message once again, stating that no manufacturing defect was found. I would like to know when exactly the shoes were sent to your R&D center for inspection between December 2 and December 7, and how the inspection was carried out to reach this conclusion so quickly. What other reason, aside from a manufacturing defect, could cause the lights to stop working when pressed or stepped on? I kindly request an explanation for this matter. Given all these circumstances, I request that the defective shoes purchased on September 8 be replaced to resolve this inconvenience. Thank you for your attention to this matter.
