As explained above, this procedure is standard with all airlines. No airline would provide you detailed documentation. The telephone reservation agent has no access to the detailed work done by the pricing department.
They reprice the ticket at the cheapest (if they are generous) OW fare, say X. Then they refund 1267.85 - X - 150.
In your case this is equal to 100.
The only additional information you could ask for is the fare bucket they have used, if you are really interested (like HLAROSW8). But you are quite lucky to get anything back, as the OW fare is often higher than the RT fare. Hence, I don't think that getting that information would help you dispute the 100.
