Please ALWAYS save (and verify) Letter of Guarantee before send us coins! If something goes wrong, we can't help you without a Letter of Guarantee. The support team doesn't have access to mixing transactions, the database is encrypted, moreover we delete all order's info after 24 hours. We keep the private key of the generated address for several days, so if you sent coins after 24 hour we still can process your order ONLY if you have the Letter of Guarantee.
