I too have become a victim of unauthorized check fraud with MX BL ent service. Someone charged my Wells Fargo account $34.99 posted 11/24/2008 with part of my name with an address registered in Hyattsville MD and I reside in Dallas TX and the check sequence number is way off by 6 digits, my sequence number still mrange with 4 digits. I did raise Wells Fargo customer service the only sugestion they made is to freeze the account.
