I ordered 3 frames - and, accidentally failed to select the acrylic backing for one of them. I reached out to see if I could get the custom sized backing and acrylic sent (paid) to complete the frame - and, they said "We cannot order that without a frame being ordered"... despite the fact I technically ordered the frame and had received it.
They also sent partially complete hardware - so, now I am waiting for one of the brackets for the frame that I technically can't use without the glass/backing...: D
Apparently I have to order a NEW frame in order to get the backing for the ORIGINAL frame I received. Not sure what kinda' business they are trying to run... but damn, not one I would ever recommend. Support your local framer - as, this was definitely a lesson learned on my part.
SAVE YOURSELF THE PAIN!
