You posted on a public forum first, calling out TRIFECTA and not providing the full story to others to gain a complete picture. We will not stand by and let these types of comments or threads spiral out of control without providing our side of the story for the rest of the community to see.
Again, we are more than happy to continue working with you if you would like.
We appreciate the feedback. This is why we have different levels of service. The Elite package provides all the customization you would want. We will most definitely work with you to get the calibration to where you want

We hope to have this released to the community soon.
