Do I lose T-Mobile Tuesdays perks if I cancel?

I took advantage of the T-Mobile Tuesday deals to snag the free years of Paramount+ and MLB.TV, but I think my willingness to tolerate 7-10 router reboots a week (which always seem to happen during work Zoom meetings) is over. If I cancel the T-Mobile internet, do I lose my free access to those services or do I get to keep them? And for anyone who has canceled or tried to cancel, how many hoops did they make you jump through to do it?
