I, too, signed up for 2 trials but canceled before they expired. However, the system is very unstable, had to do it multiple times on one of them yet still got billed, so I kept on using and successfully canceled after my first auto-billing was charged.
Ever since then, I try to use all my 10 tokens everyday but the webpage crashes constantly I had problems downloading 10 videos everyday. For instance, my re-downloads were counted as new downloads and lost my tokens to them. And when I write them about this issue, they blame me for my internet environment (ridiculous), and only compensated me the 2 tokens I asked for, valid for only a short period of time (in which hours we're in sleep here in my time zone). Therefore I never got to use the tokens lost, this went on for a couple days and in the end I said never mind I want to cancel my subscription and get money back, so they added 1 day on my subscription. I'm waiting to see if that's gonna hold up.
Seriously guys, don't use them! Go to other platforms! The free trial is sweet but make sure you cancel it before getting billed. It's not worth going through the hassle.
