But many comments here imply that chargeback is almost as easy as clicking a button or asking nicely. How's that?
Of course, if you keep on charging back, eventually your bank will give you a polite call to let you know that they're closing out your account. This provides the incentive to be relatively honest about charge backs in addition to the fact that a false charge back is a criminal offense (fraud).
If I have a legitimate charge on my debit/chequing account, I too don't know how to reverse it directly through bank.
But if I pay with visa or Mastercard (actual credit cards), I call the toll free number or go to website and start process and go through it.
Partially it's that highbibterest rates pay for policies and systems and options and insurance. Partially that credit card fraud is common so systems must be easy for consumer. E.g. I had my credit card used by somebody else probably 5 to 6 times over 15 years. They'd call me when they detect fraud,we'd go through list of transactions, and based on quick word over phone they'd cancel all transactions that weren't mine. It's a very different process than banking.

"I forgot to disable automatic billing" probably wouldn't be a valid chargeback, though.
You can log in to your credit card account, click on a transaction, and open a dispute. You have to choose a reason for the dispute. The reason has to be something like, "I was charged for a product, but never received the product."
This just starts the process. The end result may be a chargeback to the merchant.
I can log into my banks website and, selecting any payment transaction within the chargeback period, initiate a chargeback claim by just clicking a few buttons.
