Unacceptable quality

I did receive my order and I find it to be unacceptable.  The lettering is too small to read and muddy against the background.  On the mock up it looked great sharp and clear, but the printed ones are not even close to what I expected.

 

I paid for a subscription just to get business cards ~ and you threw the printing to Zazzle !

 

There is a card in one box that boasts Nikki McWilliams as the illustrator.  If this is you, I find it hard to believe that an graphic artist could have done this work.  There should have been a phone call to adjust elements if you saw that it was not readable.  Also, the order came in a snack box, so is this printing just her side hussle or a legit printing business?

 

Under your "We promise 100% satisfaction. If you don't absolutely love it, we'll take it back!" policy, I want you to take them back and refund my full amount paid, including tax and shipping. How do I return them?
