I would start by calling the 1K desk and asking to be transferred to the refunds department. These days I don't think there is a published direct line to refunds that is actually answered by a person.

You could also try filling out the web customer service form. I've had fairly decent luck getting meaningful responces recently and it's a good way to communicate details such as ticket number and dates. You can also upload any documentation you have (such as a receipt).
