The WACKIEST Cartoons of All Time! Vol. 1-5 Uncensored Animation from the 1930s & '40s 5-disc DVD set

The title says "Vol. 1-5" and "5-disc DVD set". The plastic case I received also says, "Volumes 1-5 Collection". Yet inside the case there was only a single DVD. Printed on the disc is "Volume 1" and on the disc menu it also says "Volume 1".This item is priced for 5 discs. I was promised 5 discs. I only received 1. I didn't open this up for several months after I bought it, assuming it was correct, so now I'm beyond the return/refund window. I was cheated out of the other 4 volumes.
