Auto renewal and Credit Card removal

Hey there,

Due to some university projects I signed up for a yearly subscription for CC. After my purchase, I wanted to disable auto-renewal. If I still need the service after one year, I'll renew that myself.

However, as it turns out there is no possibility of cancelling auto-renewal?! Am I supposed to set an alarm in my calendar one year from now that reminds me to cancel my subscription, otherwise I will be charged for another year incl. a 50% price increase?! (I'm on student plan, so after the first year the price increases by 50%).

So anyway, I don't want my credit card information or any derived information of it to be kept by any company other than my bank/credit card company, no matter how safe they think their system is. And as it turns out, this is not possible either?!

I'm shocked about those practices...
