changeLate, missing or wrong-network crypto payments
What to check and what to send support when an exchange payment needs review.
Start with the order and wallet receipt
Find your CS order ID and check the asset, network, amount and destination recorded by your sending wallet. Save the transaction hash or wallet transfer reference if one is available. You can provide it in support chat or email; it is not an extra field in the exchange form.
The order expired after I paid
An expired order is a payment-window status, not a blockchain reversal. Transfers can arrive after the 60-minute window. Contact support before paying again, even if the wallet already shows your first transfer as successful.
I sent less or more than requested
A wallet or exchange withdrawal fee can reduce the amount delivered. Compare what arrived with the exact amount in your order. Send support the order ID and receipt; the team will explain the proposed resolution after checking the transfer. Do not make a second payment on your own.
I chose another network or token
An address format can be shared by several networks, especially addresses beginning 0x. A successful transfer on one network does not establish receipt on the selected route. Recovery depends on the asset, network and access to the destination; it may not be possible.
My order says Processing
Payment has been confirmed and the output transfer is being handled. The saved receiving amount stays fixed. Network confirmations and payment checks can affect completion. If you need an update, contact support with your order ID.
My order asks me to contact support
An order can be paused for an AML or payment review. Contact the support team with the CS order ID. The team will explain what information is needed and the next step. A review status does not mean the exchange is completed or the transfer has been refunded.
Protect your wallet while getting help
Use the support email published on changespark.io or the site’s live chat. Support does not need your seed phrase or private key. Share the CS order ID rather than the full private status link, and do not post personal payment details publicly.
