I waited all day for my pacakage. I saw him pull into my complex and waited for the knock on my door for my package after about 30 min. I check my track number and it says not deliverable due to their not being a secured location. He didn’t even knock on my door he left a note on my mail box the package does not fit in the mail box. Now I have to pick it up on Monday when it was needed for tomorrow. Thanks USPS


I have called your listed phone # 714-546-5022 over 100 times the last 2 days and cannot get through.. Doesn't anyone there answear the phone?
