Pluto TV review: Pluto tv always buffering on inmates at racine correctional institution

Many inmates have subscribed to Pluto Tv and have paid $15/month.
Whenever they have attempted to watch movies and they get a lot of buffering that has last at least 15 minutes or more. Can someone help resolve this issue with the inmates. My husband has paid twice for this package and will not continue paying for a channel he can't get the full benefit, furthermore this channel is supposed to be free, why are all these inmates paying for this service. This is located at the Racine Correctional Institution in Wisconsin.
