Bell doesn't have them any more because Shaw Media/Broadcast dropped them. Your provider had nothing to do with the decision. Bell has no say in the programming of Diva now Lifetime. If you don't like the new programming let Shaw know or drop the channel/bundle that contains those channels. You will not be getting a discount from Bell because of Shaw's decisions.
I was thinking the same thing. We (EastLink in Northern Ontario) received a message on our DCTs early this morning that they are removing the "west feed" of TV Tropolis on October 1st. Just drop it now and while they are at it, they can drop the extra TV Tropolis east in our guide. We have it on 46 and 317. YES, I know there is no extra bandwidth used but seems stupid to have it listed in two places. Gives the illusion of more channels I guess.
