Treasury Direct Retail Sales Services review: Series I bonds

I purchased $5000 worth of Series I Bonds through the Treasury Direct website more than a year ago and have since tried to long into my account several times, without success. I followed website instruction to reset my password without success, as the site requires two separate passwords in order to access the section dealing with series I bonds and the automatic phone system only provides for resetting one password.

I attempted to reach a live person by phone and spent more than an hour on hold during several occasions only to be ultimately disconnected each time. On July 25, 2023, I sent a complaint through the website and wrote a letter to Treasury Direct Security Services, P.O. Box 9150, Minneapolis, MN [protected], detailing my experiences and requesting that Treasury Direct cash my bonds and forward the proceeds to my specified bank account. It has been more than a month and I have not received any response.
