So there are a lot of folks here that interrupt 'Adobe encrypted (DRM)' as being an EPUB format. While I don't, I can honestly say I wouldn't necessarily interpret it as PDF either. Fact is, 'Adobe' is not a format, it is company.

Without question, the vender should be more specific; can we all agree on that?

Were I the vender, I would have provided a refund.
Were I the vender, I would clarify every instance.

But also without question, the buyer should be less assumptive; more diligent.

Nevertheless: The venders description of the product is misleading at worst, unclear at best. I would dispute the charge with my credit card company. Diesel will most likely fold and provide a return. Even if they don't, the paperwork on their part associated with a dispute will incur far more labor costs on their part than any profit they made from this sale.
