I ordered from a certain online company: a piston, piston rings, and a head gasket. I received 2 piston rings and a head gasket.

I emailed the guy and he said it was my fault, I clicked the same part twice. He attached a copy of the invoice. He circled in black where I "ordered" two sets of rings. I circled in red where I clearly ordered two different things. The two part numbers on the invoice are the same, I believe they did this when they transferred the order from the internet to the invoice.

They are giving me a refund, but I'm pissed because they blamed it on me, and I had to pay almost 3x for the part locally. Please look and see if you can understand where I ordered two different things. Thanks.

Added bigger pic.

 

What are you replacing just one piston for?

 

A comp 918 broke and I want to try this because I'm too broke to buy a new longblock ATM. I don't know what will happen, but we'll see this weekend.
