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.
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.
