Wish I had a better print

The lines in the vinyl record on my design are very thin and didnt print. I wish someone on the customer service team would have looked at the original proof, and the printed stickers and said something. I realize its more of a mistake in teh design, but whoever printed these did not take the time or care to get the best print possible. Im not asking for my money back, but Im hesitant to send more work your way.
