If you are not sure about your payment, you may check the status here: https://payment-status.simplex.com/#/. Please be informed that the online payment status checker will show information only about transactions that are not older than 30 days.
In general, when the transaction is approved, the cryptocurrency should reach you in 5-60 minutes, however, sometimes, due to high market demand or other factors, delays might happen and that is completely normal.
If your crypto does not appear in your wallet within 3 hours after the transaction was approved - please contact our support for further investigation.
