Bitcoin transactions can be written to support escrow use cases.

*Edit: Transactions can be sent to a script which requires multiple keys to forward the funds from that script address to a wallet address. https://en.bitcoin.it/wiki/Multi-signature

This is the primary mechanism for escrow services to function. If the need for a CC-like refund feature is important to the user, one could potentially use a service over Bitcoin which is party to a 2-of-3 multisig transaction. The payment may be settled immediately by the buyer and seller. Or either party may dispute with the service provider to settle according to some agreement.

To perform escrow with that technology a trusted third party is required, at which point, you are resolving disputes exactly the same way it works with credit cards: you are convincing some organization that the transaction wasn’t satisfied.

True, but then we‘re no longer talking about Bitcoin.

The settlement layer is rarely the most interesting part of a retail payment system.

How? It's direct from wallet to wallet
