Identify what the two amounts represent
As a practical comparison, keep the merchant receipt, the authorization amount and currency, and any later finalized amount and date. A reservation shown before finalization and a completed charge need different explanations. Do not subtract two numbers without checking that they describe the same purchase and currency.
The status guide explains the labels. This article focuses on a reserve above the expected purchase, not a promise that every unfamiliar deduction is temporary. If the transaction itself is unrecognized, use the official reporting process rather than assuming a hold explains it.
Why merchants may reserve more
The official higher-charge article describes a hold for possible additional spending. Its examples include hotel or car-rental extras, an estimated restaurant tip, gas-station reserves and ticket-price changes. It says the amount is usually adjusted when spending is finalized; it does not give a universal reserve size.
Ask the merchant which amount is the reserve and which is the final invoice. This publisher has not booked a room, rented a car or made a test purchase, and cannot establish a merchant-specific amount from the card record alone.
Ask whether a refund was actually processed
If the charge remains above the agreed purchase, RedotPay directs users to confirm the refund status with the merchant. The source distinguishes a merchant-processed refund from one not yet processed. It describes 2–15 days for credit after RedotPay receives the former and a typical merchant processing period of 30–40 days in the latter branch; these are source timing descriptions, not an approval or arrival guarantee.
Keep the merchant response and refund reference. Do not count time only from your initial complaint or treat a requested refund as a processed one. The refund guide covers the separate credit-status investigation.
Keep a currency adjustment separate
A foreign-currency settlement difference can have another explanation. Before assigning the whole discrepancy to a reserve, compare the currencies and final invoice and ask support which stage changed. Do not assume a larger number proves fraud, a fee or a duplicate charge. Use official support for your transaction and keep private records out of public comments.
Codes do not release a hold
SAVE2 is for an eligible virtual-card order; DZ100 is for an eligible physical-card order. Enter the matching code in the promo-code field at card checkout only when that card and field are offered to your account. Check current issuance restrictions, physical delivery where relevant and the final app total before paying. The operator reported the codes usable on October 27, 2026; this publisher did not perform a fresh checkout-price test. Read the card-order conditions.
These codes do not release reserves, reduce merchant bills, waive a chargeback fee or create a refund. They are card-order promotions only.
Frequently asked questions
Does every higher amount mean an extra card fee?
No. The official article describes merchant authorization holds above expected spending. Compare status, receipt and currency before deciding what a difference represents.
Does requesting a refund mean the merchant has processed it?
No. Ask the merchant to confirm processing and retain its reference; the documented credit stage depends on receipt of the refund.
Can SAVE2 or DZ100 release a reserve?
No. They are eligible matching virtual/physical card-order checkout codes, subject to current conditions; they do not release holds or discount merchant bills.
