Assuming that you did Cancel it successfully, and didn’t run into any of the issues that @schnapps has laid out, cancelling on the 6th day can still be too late, as even though you get the whole 7 days free, Now often have to start the billing cycle on the 6th day in order to meet the banks’ deadlines.
It’s best to cancel a free trial straight away, therefore.
Which perhaps sounds like odd advice, but it will still run for the full 7 days; what you are really cancelling is just the renewal.
And if you decide you do want to continue, you can just unCancel it, and let it run seamlessly into the paid service.
