UPI error ZQ: Unable to process reversal
Raised by: Bank / PSP. Source: NPCI, UPI Error and Response Codes v2.9, section 3.1, codes populated by banks and PSPs.
What it means
The reversal couldn't be processed. NPCI marks ZQ as reserved for future use; the codes used in practice for reversal failures are U32 and U33.
Not fully documented: Reserved for future use in NPCI's list.
Possibly. The final status wasn't confirmed when this code was raised. Check your statement before paying again.
If the payment ends as failed, the money is due back by T+1 for a transfer to a person, or T+5 for a payment to a merchant. Don't pay a second time until the status is final.

Business: the systems worked and declined the payment.
What you should do
If money left your account, raise a complaint in your UPI app with the transaction reference. RBI's deadlines for reversal still apply.
If you are a merchant, bank or PSP
Track it to closure through the dispute process.

If it still isn't sorted
- Raise a complaint inside your UPI app. Every UPI app has a help or dispute option on the transaction, and it goes into NPCI's online dispute system. Keep the UPI transaction ID or RRN handy.
- If the app doesn't resolve it, contact your bank's grievance desk with the same reference.
- If your bank hasn't replied within 30 days, or you're not happy with the reply, complain to the RBI Ombudsman at cms.rbi.org.in. It's free.
Technical or business decline?
NPCI splits declines into two kinds. A technical decline means a system didn't respond or failed: a bank offline, a timeout, a switch error. A business decline means the systems worked and said no, for a reason about the account or the payment: wrong PIN, not enough money, a limit, a risk check. Retrying helps with some technical declines and almost never with business ones.
