This could boil down to a my word versus his word situation and I don't know how we could assess blame. Your complaint sounds very reasonable and believable. I'm convinced that those are accurate images of the books you received and they aren't as advertised.
Is there any chance they could have been damaged in shipping?
The mailer looks fine. Could something have crushed it, maybe, no indication though. I offered him that explaination as opt out.
If I bought this from Amazon, metropolis, bob storm what would they do? Offer a refund, keep the customer happy. Standard return policy, I didn't think it needed spelling out before the deal was done, lesson learned. If it was a "switch", really for $17 copies. I was not even going to bring to probation thread because I didn't want to cast any shadow on my name/rep. But in our PM he was antagonistic and that is why I brought here.
