I'd rather speak to the postmaster for this location. Both of the phone numbers I have been given by usps go unanswered and do not offer voice mail. I have a missing check, sent by certified mail, that has not been delivered to a residence in the 78701 zip code. I have directed redelivery on line, and when it was not redelivered, I called the usps toll free number, where the service agent confirmed the situation and typed in directions to redeliver again. Still no delivery, and no updates have been made to the tracking record. Carrier never left a note about missed delivery. Please respond with a direct phone number (with voice mail capability) or email address for the postmaster Tracking #70160600000068291161 Confirmation #TRR79549930
