I got a 15 GB account with Mega. I activated a bonus and got about 5 more. It's full now, but I forgot about that fact until I got an email about that I need to upgrade—bonus has expired —, or they're going to delete the data. But until I do, I can't delete the data, I can't do anything except pay, or everything's gone. So, I guess everything's gone. There is no way I'm putting my card on a service that kidnaps data.

AFAIK 20GB is now free forever for active accounts, so that email might just be a reminder to log in to refresh it.

If not, you can also subscribe via Google Play or the App Store and keep your payment info safe that way. (I didn't sign in to check if they support PayPal or the like)
