How do I contact someone regarding a order

threw EBay commerce which has not been received

I really do hope you purchased from a reputable seller, and not a dodgy random registered in China or dropshopping from there as doing so will result in a poor quality product, likely to put your pet in danger of injury or worse

What is the item number?
