If you paid for parts based on the picture shown on the vendor's website, you should receive what is pictured.
Personally, I would have approached it from that angle, I ordered based on your picture and what I received isn't what was pictured.
I understand pictures can be representative but that's getting weak these days with online sales. The vendor should have an exact picture online of what they are selling. Yes, it's a pain to setup but that's part of doing business online.
I'd call the vendor back and have another conversation.
