Corporations That Probably Won't Get Repeat Business

I finally paid off my Chase card, only to find a service charge for $2.93 on the next bill. Now, I had contemplated closing the account because they had told me they were going up on my interest rate, but I hadn't done anything. $2.93 is a small amount, but it was enough to make me pick up the phone and close the account right then.
I suppose I'll pay them the $2.93, but seriously, what is it for?

I decide to try a pre-paid phone service- much cheaper for me than what I was paying Verizon. I call Verizon on the 11th, but since the billing cycle ends on the 4th, I get this spiel- they don't want to pro-rate, so even though I made it clear the phone I have from them doesn't work, they still are billing me for the full time. So I have their phone, which won't hold a charge, sitting on my mantle.
$40+ down the drain.

In both cases I didn't have a particularly negative view of the company. Chase was just doing what credit card companies did, and Verizon is an okay cellular company- they just weren't providing a package that made sense to me. But they've just lifted the bar higher if they ever want to get me back as a customer with these extra charges.

I've also started to think there's something unjust about how they do stuff. Chase can send a notice to me about how they are going to change terms. I am supposed to do something if I don't like it, but otherwise the terms will change if I don't do anything. Let's look at it the other way- what if I sent them something? If they do nothing, will what I ask for take place?

Or will they use government, credit agencies, and whatever else to get what they want out of me?

This isn't a free market.
