Is my t-shirt logo placement incorrect on Bella & Canvas?

Hi I created my t-shirt with the logo on the top of the upper back. Small logo like 4 inches by 4 inches right up at the neck. With the bella and canvas t-shirt it all looked great. Then when I get the t-shirt the design was 4 inches lower. Is this an error on the printing? How can I tell if the logo is 2 inches from the neck on the back? Thanks
