Bailey's Head and Neck Surgery: Otolaryngology (Head & Neck Surgery- Otolaryngology) Sixth Edition

I got only volume 2… It is supposed to be a 2 volume set! Also it was damaged.

I ordered this textbook which suppose to have 2 volumes, 1 and 2. However, after I open the box, there is ONLY 1 book inside, volume 2. (Volume 1 is missing!) What should I do?
