The mounting plate does not fit - Burris FastFire Reflex Red-Dot Sight Mounting Plates

I recently purchased the Burris FastFire III Red Dot Sight and a Red Dot Sight Mounting Plate to fit my S&W M&P 2.0 9mm Compact. The mounting plate is milled with a slight concave under belly that is supposed to fit the top of the slide, the problem is, the slide in the M&P 2.0 is flat. The mounting plate I received marked S&W M&P # 410336 must be designed and milled for the original M&P not the 2.0. Somehow, no one realize the difference or failed to add this little bit of information in the product description. I have reached out to Burris on two separate occasions, but apparently, no ones home. I hate to send the entire order back to OP, I don’t think they are the faulty party here. The mounting plate will not seat snugly to the slide, therefore, rendering the Red Dot Sight useless. I contacted OP for some help and as always they said return the items. I hate to do that, but I’m afraid I have no choice. Thank you OP for standing behind your customer service pledge.
I guess if Burris had answered my request for help, or at least explained why the mounting plate was Not designed for the newer 2.0 models, then I wouldn’t have given them poor rating.
