UPDATE:
So I check my work email this morning and saw that I FINALLY got a response from Overdrive. Turns out, yup, my emails were going straight into a spam folder. They checked their records and oops, they did indeed send me the wrong EMS tracking number.
So I check the correct number they gave me and....the package containing the statues (yeah, they had all three!) was sent out on the 17th, and arrived back on the 19th! Apparently, they postman tried delivering it on 19th but I wasn't here (my shipping address is my work address) and didn't bother to leave a delivery notice. I didn't find out about it until today!
Sooooo, today I picked up my package at the post office and this is what I found inside:
And my bonus items?
So yeah, I'm happy I finally got everything, but the email and tracking number snafu has really left a bad taste in my mouth.
