I would like to publically thank (as much as I can here) the company "Learning with Linden ".

They have sorted me out with the brackets for a projection screen that was delivered in a poor state by the vendor. The vendor has been difficult to deal with on this problem, but looking over the delivered package I noticed a name on it that included a model number. By googling that name I found "Learning with Linden" and from there I was able to find the product.

I was able to call them, explain my situation and after they verified I had purchased the product they said they would send me the brackets tonight in the post! Wonderful, well, I will see and perhaps update you.

Edit:
To update you, it went up, it doesn't look great, but then again you get what you pay for in life, and it didn't cost much.
