Alibris review: Incorrect postal address used - no book delivered and no resolution

I ordered a book from Alibris Books via the Walmart website. Yesterday, the post office indicated the book was delivered to the address I provided them, but it was NOT HERE! I searched every doorway in case the postal worker brought the item to the door. IT WAS NOT HERE! The search happened 10 minutes,after it had been marked delivered. I noticed the delivered notice said it was left at a parcel locker. WE HAVE NO PARCEL LOCKER HERE! So I went out to the Post Office and got tge phone number of the Post Master General's office and reported the problem to them. The clerk told me the tracking number had another address listed, not mine. So she said to have the company ( Alibris) call them to discuss the descrepancy. Meanwhile, Alibris sent a message that the address they used was what I gave them. It IS NOT. They were told to call the Post Master General's number to inquire what address is there. I have informed them I will be sending this complaint on to the Iowa Attorney General's office who can investigate this and request what address was used. This is the WORST form of customer service I have encountered. Something seems awry with all of this!
