From what we can see from our side , we can only check your whalecode it has been manually deleted before the mixing took place
If user manually deleted the logs , we have no access no any information to where the coins were suppose to be sent or which address it came from
This is a very important security features that we do to ensure the logs are destroyed and with no backup to ensure our clients security

Kindly email us with the transaction reference or blockchain reference , if the unmixed balance matches the amount you mentioned , we will refund back to your address that you sent the funds from. We will not collect any fees on this , however the miners fee/ transaction fee will be imposed for the transaction.

Kindly note that this happened because user manually deleted the logs before the mixing could be performed as the receiving address is permanently deleted once this actions has taken place.
