I have NEVER had this issue before, especially with tracked items to my office.
My co-worker ordered something, to be delivered to our office. They attempted delivery on Saturday when we were closed (duh). They "apparently" delivered it today at 9:12 a.m. I have USPS tracing the package.
Meanwhile, I ordered something a few days ago (completely unrelated to my coworker), and it was supposed to be delivered today. It was "delivered", at 9:12 a.m. as well. No package got to me today. This was fairly expensive, so I'm sitting over here trying not to freak out, that it's just sitting in our mail room for tomorrow morning.
Does this seem suspicious that BOTH packages were apparently delivered at the exact same time and DIDN'T show? I KNOW I gave my correct address, and I reconfirmed the address on my coworker's package. Both were correct.
I considered it a safer alternative to leave an expensive package outside on my home doorstep. In fact, I mailed a bunch of stuff to myself that I bought while I was on vacation a few weeks ago. No issues then. Eesh! Hopefully I'll have a better update tomorrow. I'm off to bite my nails, in the meantime.
