What if I wasnt able to pay my Adobe CC sub or if my credit card runs out of money?

Q: What happens when I don't pay my phone, electricity or water bill? 

A: The service is shut off.

It's the same with your Creative Cloud contract.  I suggest you work this out with Adobe or you will pay for it in other ways later.

If you sign up for a contract, it doesn't go away because you can't pay or find a way to stop paying. Instead, the debt will continue to increase, and may be handed over to debt collection agencies, who will chase you for the debt and charge large extra fees. You can't break your promises so easily. You promised to pay for a year. Adobe do allow you to cancel early and generously charge only half what you promised (that is, the cancellation fee is half what remains to pay in the year; you must owe $800). I suggest rather than going into this area, which may be expensive, you at least contact Adobe and explain the situation. TAKE CARE THOUGH (1) don't respond to private message from "Adobe", these are scammers (2) if you are offered a couple of months free, then at the end of the time you are committed to pay for a full year again. $800 suggests the program only just started, Adobe may have flexibility, if you are nice. Yes, it's in the hands of the agent.
