I placed Order #245842147501026888 through Alibaba with supplier Shenzhen XYZ Tech Co., Ltd for a custom elevator project requiring technical drawings and adaptation to a laminated timber house.The supplier ignored all requests for documentation (CAD files, profile drawings, installation specs), and started production without approval — violating the agreement and creating a major safety risk.I filed a refund request and formal dispute on March 28, 2025. Today is 30.04.2025 — and after more than 20 days, Alibaba’s dispute team is still “mediating,” sending template messages while refusing to address the technical breach.This is not a shipping delay — this is a serious contract violation. The supplier was unprofessional, dismissive, and Alibaba has done nothing to protect me as a buyer.I have filed a chargeback with my bank and submitted a formal complaint to Chinese regulators.Buyers beware: Alibaba’s “Trade Assurance” does not assure anything when things go wrong.
