Overnightprints.com Overnight Prints Poor Quality, Poor Customer Service, and No Resolution Internet

I went to overnightprints.com to order business cards for all members of the company. While on the site I "chatted" with 2 different people on different occasions requesting help on having my design reach the bleed mark. Both times the people were not helpful and seemed unknowledgable of the design feature of the website anyway. One told me that the uploader will accept a pdf when it obviously was only allowing a jpeg. The other gave some bogus instructions. So, I saw on the final preview that my design will still look good without the bleed mark. It is perfectly centered and square. I'll take it. However, when I received the cards there is not 1 card printed correctly. The back of the cards are off center and some are even cut where I can see color from the next card cut off onto the previous one! Horrible job. Sloppy. Lazy. Terrible. I contacted them and demanded a reprint. After uploading photos of the cards I stated that a refund is acceptable. I was told that my request was denied since I did not pay extra for a design review that would catch errors before printing. After pointing out that it was not a design error- the final preview was perfect and the reviewer would have caught nothing because it is a printing and cutting issue, not a design issue, I was told that they are allowed a margin for cutting to be wonky I guess although business cards are small and the tinest shift makes a huge difference. These cards are completely unusable! It is a crap job. And I intend to be compensated for horrible service.
