Redemption of Bond Funds Lodged w US TREASURY

I am new to this process.

My bond has been lodged with the US Treasury for about 5 weeks now. Have created a Promisdory Note between my business and my soverign trust. Have bank accounts in the same bank for the Trust and my LLC/business. Want to proceed with a Treasury Direct Transfer or the optimum process to fund the business bank account, via the UST Discount Window only accessible by a bank. The commercial side of the bank does not seem to understand that it is legal and possible to access a private account within the UST, nor that non-US Treasury bonds or assets can be lodged in a private Trust acct in the UST. Further they indicate that the US Sec of the Treasury/ et al can be a fifuciary on my behalf. Please advise as to specifically how-to-proceed with the bank, the "optimum" contact within the bank, in a step-by-step procedure.

Thanking you in advance for your historically successful advise and counsel.
