If you're using escrow or planning on it, it's not a requirement but we do prefer if you can email us with your txID, payout address and signature details for your payout address (and payment address if its different) as well. That way we can back your case better in future if there is a problem as well as manage the billing and customer service better.

If you've already sent a payment through John K. and would like quicker response times and better service then please email us the above details to info@ultibit.com
