Terrible customer service

Terrible customer service. I ordered a stand for my bike following their filtering to make sure it's the right one for my motorcycle and they send me an item that doesn't fit my motorcycle.

I contacted their customer service trying to find a solution but they didn't provide any help at all and said they couldn't refund or let me return the item because I had opened the package.

How was I supposed to know that they send me an item that doesn't fit my motorcycle.
