This is the LUT pack I use in my every video.
There are 2 Luts one is Base Lut and one is Final Lut.
Firstly you have to extract the .zip file you download and then you will see 2 lut files. Please watch the video link I attached to see how to apply correctly.https://youtu.be/PdtQPZEj0rM
Once purchased, there is no refund available.
