I had Sling TV orange for 1 month around Jan 1, 2018 for college football Bowl Games (ESPN), then cancelled subscription. Had Sling TV blue during February 2018 for the Winter Olympics (NBCSN), then cancelled subscription. I currently don't have a Sling TV subscription; but have signed up maybe 8 times to Sling TV since the service started (1 month each time), and have never had Sling TV re-activate itself or charge my credit card without my consent. My last Sling TV subscription was Blue 2/10/18 to 3/9/18. Checked my online banking on April 22, 2018; and about once per week and never see any Sling TV/Roku ERROR CHARGES. I have Netflix all year; so occasionally use Sling TV for bowl games, Olympics, etc. I use a Premiere+ and Roku 2 (4210) for Netflix & Sling TV.
