This bad rating isn't reflective of the store as a whole, but in the framing department. I went in to get a series of prints framed. I knew what I wanted and assumed it would be straight forward to order. The lady whom I spoke with was far less than helpful.
She said I NEEDED a matte. When I politely refused her suggestion of a 4" matte, she said, "Well I guess I could do a 1.5" matte" (Implying I was inconveniencing her to do something out of her comfort zone). Next she suggested frames that I was not interested in. Again, I declined saying I wanted something simple. Her reply back was "I'm told I have an eye for this thing." Be that as it may, you clearly don't have mindful customer service.
I frequent joanns on a weekly basis. I love their fabrics and appreciate their amazing deals. Do yourself a favor and go to Hobby Lobby for framing. They listen to what their customers want and will give you a better deal.
