This product is not able to be clipped on to rifle scope - Burris BTC 50 1x50mm Thermal Clip-on Monocular

I bought this Thermal Clip-on 5 months ago. When I bought it I believed I was going to be able to use it as it was advertised.
I live in Alaska and planned a hunt in Texas for wild hogs, if you have ever been to Alaska you know it cost a lot of money to travel out of Alaska and a long flight. When I received my Burris Thermal Clip-on, there was no clip-on attachment with the Thermal. When I called Burris
they told me that the clip-on attachment wasn't available, but would be in 2 or 3 weeks. That ruined my planned hunt, I went on the hunt, but wasn't able to hunt at night like I wanted. The problem is Burris keeps saying that the Thermal Clip-on attachment will be available in 2 or 3 weeks, But yet it has been 5 months now and still no attachment. When the Thermal Clip-on Attachment does become available they expect me to buy it for $189. even though when I purchased the Thermal Clip-on they didn't say it was sold separately or that it was not available.
Burris has the worst customer service I have experienced. It is sad as all my riffles and handguns have Burris scopes. I have been loyal to them, but they don't care.
