Quick update - I did get my money back after continuous excuses.
I took the piece to a highly respected frame shop to inquire about a few things.
First thing I asked was "If I bring in a poster can you take measurements and build a frame without me leaving the piece?"
Response: "Yeah we could probably do that but why?
Me: "Because if you screw it up or lose it I can't go replace it from Walmart"
In the bottom right hand corner the printing company typed their company name is small letters. I told the framing guy I would like the mat to be notched out so this would still show. He said "just write it down on a piece of paper and stick it to the back."
Are you kidding me?? Im the customer and do what I want! Is it really that difficult?
I left the store....I may have to figure this out on my own.
