Free & lifetime upgrades.
I am Shirley from Digiarty Support Team. For downloading online video, our program will display all the available video and audio tracks for the original video, and you can select the one you need to download. And there are also many ways to improve the quality of the target file, you can contact us for detailed directions.
For the rude customer support, it must be a misunderstanding. We treat all our customers kindly and one business day reply is guaranteed for all the emails.
Ps, we will upgrade our program constantly to meet your needs and all our paid customers can enjoy free & lifetime upgrades.
