Important Tip
To speed up resolution:
1.Take photos of the delivered parts (counted and grouped if possible) and the packaging slip (which lists the ordered quantity) as evidence.
2.If you received fewer parts, confirm whether the missing items were possibly split into separate shipments (common for large orders) by checking your order logistics details first.
3.If you received extra parts, inform our team immediately to avoid delays in arranging return or compensation.
