The only one that looks weird is your first story with your ISP. Never heard of that. I have comcast, so talk about scumbags, and the one time my connection was degraded they sent a guy for free to replace some cable or I don't know what.

Everything else looks "standard". Security services are a scam by design so of course they make it hard to cancel. Banks do weird stuff like that, could be regulation, could be old systems. As for your phone, looks normal to me for the provider to tie promo and deals to a minimum contract duration.
