Subject: Re: Order #48821 — Still waiting
Hi,
I've now been charged twice for the same order and I've been trying to get this resolved for over two weeks. I already spoke to someone last Tuesday who said the duplicate charge would be reversed within 3–5 business days, but I just checked my bank statement and the money is still not back. At this point I'm not even sure I want the product anymore — I may just want everything canceled and a full refund. But honestly, first I just need someone to explain what's happening with my account because this is completely unacceptable.
Please respond ASAP.
— Deborah

Expected Output
BILLING_INQUIRY — Although the email touches on frustration (complaint), a potential cancellation, and a possible refund, Deborah's most immediate and explicit request is for an explanation of what is happening with the duplicate charge on her account, making billing inquiry the primary intent.

BILLING_INQUIRY
Justification: While the email touches on multiple issues (duplicate charges, refund possibility, and frustration), the primary intent is to understand and resolve the billing problem—the duplicate charge and its status—which takes precedence over the secondary mention of potential cancellation.
