How do I open a dispute?

Short answer. Open a dispute when a vendor has gone quiet past a reasonable window, when the order is well past its shipping time, or when what arrived does not match. Bring clear evidence and a calm factual account.

What a moderator reads

Your account, your evidence, the full message thread, and the vendor's dispute history. The evidence you bring up front is what the decision turns on.

Improving your odds

Keep the language factual, not accusatory. Answer questions quickly. Do not open several disputes at once. And never finalise early hoping a vendor will reward you by shipping, because that removes the dispute path you would then need.
