Why does a casino bonus balance show as unavailable, or why has a withdrawal been held after play? For a New Zealand player, the answer may depend on the bonus rules that applied when the offer was accepted, the games played and the account’s transaction history. Keeping those details together makes it easier to check what happened.
If you are reviewing a bonus at Cosmo Casino, save the offer and its full terms before opting in or depositing. This guide explains which records can help verify a wagering requirement, what to ask support for, and how to compare the casino’s calculation with your own. It is about documenting a specific bonus issue, not assuming that every promotion uses the same rules.
Start with the bonus terms that applied
Promotional wording can change, and a short banner may not show every condition. Record the offer name, bonus amount, date and time you claimed it, and the terms page or message shown at that point. If the terms are available only after signing in, save a screenshot or permitted copy for your own records. Make sure the capture shows enough context to identify the promotion.
Check for the exact wagering multiplier and what it applies to. A requirement may be calculated against the bonus, the deposit, or both. Also note the expiry period, minimum qualifying deposit, maximum bet while the bonus is active, eligible games and each game’s contribution rate. Look for withdrawal limits, excluded payment methods and any rule about cancelling a bonus. Do not rely on a general promotion summary if the detailed terms are available.
Keep a clear evidence file
Use a folder or dated note so the key records are easy to find. Keep original files where possible, and avoid cropping screenshots so tightly that the date, account area or offer name disappears. A simple checklist can prevent a support query from turning into several rounds of missing information.
- Offer evidence: screenshots of the promotion, full terms, opt-in confirmation and any message confirming the bonus was added.
- Account evidence: the bonus balance, wagering progress, status messages and relevant account history, with dates and times visible.
- Transaction evidence: deposit and withdrawal references, amounts, currency, processing status and payment method. Keep bank or wallet records that match the casino entries.
- Play evidence: game names, session dates, bet amounts and round or transaction references where available. Note any game that may have a different contribution rate.
- Support evidence: the case number, date of each contact, the question asked and the complete reply, including any explanation of the calculation.
Never send a password, one-time security code or complete payment-card details to prove a claim. If identity documents are requested, use the account’s secure verification process and follow the stated instructions.
What to request if the figures do not match
First, write down your own calculation using the terms you saved. For example, list qualifying bets, remove rounds you believe were excluded, and compare the remaining eligible stake with the progress shown. Treat this as a check, not proof that the casino’s figure is wrong: contribution rates and game restrictions can change the result.
| Question | Useful detail to request |
|---|---|
| How much wagering remains? | The qualifying turnover counted, excluded play and calculation period. |
| Why is a game absent? | The game’s eligibility and contribution rate under the terms for this offer. |
| Why is a withdrawal pending? | The relevant bonus condition, status and any action still required from you. |
| Which terms were used? | The version or offer record linked to your claim date and account. |
Ask for a specific explanation tied to your account and the promotion, rather than a general description of bonus rules. Include the relevant timestamps and transaction or round references, but share only the information needed to locate the issue. Keep the reply with your evidence file.
Optional records that can strengthen the timeline
If the issue involves a deposit not appearing, include the payment provider’s transaction reference and the casino deposit status. If a balance changed during a session, note the game, approximate time, stake and displayed balance before and after the round. A screen recording may help when the problem can be reproduced, but do not edit it in a way that obscures what happened. Keep a short timeline in New Zealand time and state if a receipt uses a different time zone.
One setup mistake to avoid
Do not accept a second promotion or make another deposit while you are still checking which offer is attached to the account. Overlapping offers can make it harder to identify the applicable wagering conditions or payment history. First confirm the active bonus name and status in the account, then save the relevant terms before taking further action.
Practical verification before contacting support
In 2026, take five minutes to compare the offer record, account history and your transaction notes side by side. Confirm that the dates align, the currency is clear, and each claimed game or payment has a reference. Then send one concise support request: describe the difference, state the calculation you used, attach the relevant screenshots and ask which term or transaction explains the gap. This gives support a verifiable trail and leaves you with a clear record if you need to follow up.
