Directv WVB Mounting Plate

Hello. I got my service installed and the technician installed a WVB for my mini wireless clients. Only issue is that I cannot wall mount my bridge. Per the manuals the bridge should have came with a mounting plate the bridge slides on to after the plate is screwed onto the wall. I have called a few technicians that have left me their phone numbers, but they all claim that the bridges do not come with the mounting plates. Which I do find weird, because in the past I had the same setup in my previous home and it that one came with the plate. 

What I have been told recent was to mount the bridge straight on to the wall. But the way it was designed, if I were to do it that way, the bridge would be hanging off horizontally.

Would anyone know what would be the best way to obtain the plate?

I attached a picture that shows the plate to the left of the bridge. I would hate to buy a whole new bridge just for that plate.

It may sound like a silly complaint, but I have an OCD for having my things all organized and wall mounted lol.
