You must viewed your video more clearly. Wecan't see it clearly what is you mean by you can't stop the roll. Maybe your mouse isn't connected with your PC or whatever. Try to re-make the video to prove if the autobets can't be stop on your side, which it never ever happened to us.
His complain is fully baseless and the video doesn't prove anything. He should provide a stable video where we can see everything clearly. In this video I can see that he is continuously clicking on his mouse and also shaking it a bit. But the mouse pointer was fixed over stop betting option. It didn't even move for the shake of mouse. Maybe the mouse wasn't working or his device is slow to catch the command. I haven't faced any problem at wolf.bet while betting.
