It’s 1.4 patch day, Miyabi’s limited banner is live, and you just swiped for the $99.99 Monochrome pack to hit your 76-pull pity — but the Polychromes never show up. Your bank confirms the charge went through, but your account balance remains untouched. You’re far from alone: the ZZZ community flagged a 40% spike in RET 107 errors during launch week, triggering 24-hour delivery delays and accidental bank blocks right when every pull counts.

Why Payment Failures Hit ZZZ Hard

RET 107 errors and greyed-out purchase buttons usually trace back to three root causes: active VPN usage during checkout, regional mismatch between your registered HoYoverse account location and payment method billing address, or automated bank fraud filters that flag Cognosphere (HoYoverse’s parent entity) as a high-risk international merchant. Community spreadsheets tracking failed ZZZ purchases show that 32% of failures stem from user input error: mis-typed 9-digit UID or incorrect server selection, a mistake disproportionately common when players top up for a friend on the America server while actively playing on an Asia account.

Immediate Triage: Force Delivery Without a Refund

Wait a full 24 hours before submitting a support ticket. HoYoverse’s server-side reconciliation system resolves 78% of pending banner-launch charges within a day, as servers are overloaded with thousands of concurrent top-ups during new drop windows. Force-stop the mobile app or fully exit the PC launcher, then re-log into your account: this triggers an automatic missing-item check that often pushes delayed Monochromes and Inter-Knot Membership rewards straight to your in-game mailbox. Cross-reference your transaction history on the official ZZZ Top-Up Center. If your transaction shows a "Success" status, your Polychromes are queued for the next 15-minute server sync wave, and no support ticket is required.

Official Support Without the Ban Hammer

Worried your missing Polychromes won’t arrive before Miyabi’s banner ends? Never initiate a chargeback directly through your bank. ZZZ’s anti-fraud system automatically deducts the equivalent value of Polychromes from your account, leaving you with a negative balance, and gives you a 7-day window to re-top-up the missing amount before issuing a permanent ban for fraudulent refund activity. The only safe way to request a manual check or refund is to email zzz_payment@hoyoverse.com with your 9-digit UID, registered server, and official transaction ID from Apple, Google, or your bank: this triggers a manual delivery verification that won’t flag your account for fraud.

A Safer Path Forward: Why Proxies Are Switching to Lootbar

Minimizing top-up failure risk during high-traffic banner windows cuts down on lost pity progress and avoids unnecessary support follow-ups. Veteran proxies often use Lootbar for faster, more reliable top-ups, as the platform pre-handles regional routing and payment authentication to sidestep RET 107 bank blocks and greyed-out button errors that plague direct card purchases during launch windows. The platform’s dedicated ZZZ top-up page at https://www.lootbar.com/top-up/zenless-zone-zero validates your UID and server before processing any transaction, eliminating the 32% user-input error rate and guaranteeing delivery even when official servers are running behind.
