IEEPA Tariff Refunds from DHL as Importer of Record

DHL was the importer of record on a bunch of my shipments. They've only processed one IEEPA refund and I have no visibility into the rest.

They won't tell me which shipments they've actually filed claims on. Even my account rep can't give me a straight answer on what's been submitted. Worried time may run out and I lose the ability to get those refunds.

Questions for anyone who's dealt with this:

• Has anyone gotten all their IEEPA refunds back where a carrier was importer of record?
• Did you get any confirmation of which entries they filed on?
• What worked to push them or escalate past the account rep?

Also, for anyone who received the refunds, did they just refund back into your DHL account as a credit? I want to get our refunds back onto our original payment method (credit card) so I can put them towards other expenses, not just DHL invoices.
