Before making a deposit, save a copy of the bonus or promotion terms you intend to use, including the date shown. This resolves a common uncertainty later: whether a wagering requirement, expiry time or withdrawal condition has changed since you joined.
For a brand-specific starting point, review the current New Zealand-facing information at Cosmo Casino, then compare it with the terms displayed in your account. Keep records that show what you saw and did, rather than relying on memory; dated evidence can help you ask a clear question if a deposit, bonus or withdrawal does not go as expected.
What to verify before starting
Read the terms for the particular offer or account feature you plan to use. A headline amount alone does not show the full conditions. Check the operator name, eligibility, qualifying deposit, minimum odds or game contribution if stated, wagering requirement, maximum bet while a bonus is active, excluded games, expiry, and any withdrawal cap. Note whether the terms say that accepting an offer changes which funds are used first.
Save the complete terms, not just a cropped promotional image. Use a screenshot or print-to-file copy that includes the page heading and relevant conditions; record the date and time. If a condition is unclear, ask support before opting in and retain both your question and the full reply. Ask for a direct answer about the exact offer, rather than a general explanation of bonuses.
- Account and identity: Check which name, date of birth and contact details must match your documents, and what verification may be requested before a withdrawal.
- Payments: Confirm supported deposit and withdrawal methods, processing expectations, fees if listed, and whether the payment account must be in your own name.
- Promotion: Record the offer name or code, opt-in step, start and end times, wagering calculation and restrictions.
- Games: Check whether a particular title contributes fully, partly or not at all towards a bonus requirement.
What to check during use
Keep a simple transaction trail as you play. Save deposit confirmations, withdrawal requests, account-history entries and any payment-provider reference numbers. For a card or bank transfer, retain the confirmation showing the amount, date, currency and transaction identifier, while masking unrelated account details if you share a copy with support.
If a balance or promotion looks wrong, capture the account screen promptly. Include the visible balance, bonus status, game title, date and time, and any error message. Take a second screenshot of the relevant terms or offer status if it helps explain what should have happened. Avoid editing the original image; make a separate redacted copy if personal information needs hiding.
| Issue | Useful evidence |
|---|---|
| Deposit missing | Payment receipt, amount, timestamp and provider reference |
| Bonus not credited | Offer terms, opt-in proof and account bonus history |
| Wagering dispute | Terms version, qualifying activity and bonus progress records |
| Withdrawal pending | Request confirmation, status history and any verification message |
When contacting support, state the issue in order: what you expected, what happened, when it happened, and what you would like checked. Attach only the records needed to identify the transaction. Keep the case number and the full conversation, including dates and any promised follow-up. If a reply refers to a rule, ask for the specific term and the version or date that applies to your account.
What to retain afterward
Keep a folder with the terms, screenshots, payment records and support messages together. Use filenames that include the date and subject, such as “2026-05-14-withdrawal-status”. Store original files securely and avoid relying on access to an account page that may later change. Retain records for as long as you may need to query the transaction, subject to your own privacy and storage needs.
After an issue is resolved, save the final outcome as well as the original complaint. A credit, reversal or explanation may appear in a later account statement, so compare it with the case response. If the answer remains unclear, your collected timeline makes it easier to explain the matter consistently when seeking further assistance.
One preventable failure: keeping only the promotion banner
A banner may omit important conditions or disappear when an offer ends. Relying on it alone can leave you unable to show the wagering rule or expiry that applied when you opted in. Save the full terms and proof of acceptance before depositing, then keep the transaction trail as you go. That small step gives you a clearer basis to check a bonus calculation, question a payment delay or identify which condition needs explaining.
