Billing Etc.

Hey guys, I had to download adobe photoshop for a photo class and now It's holding me hostage for a service I will never use as my University already has the programs. Its going to charge me around $100 to cancel after using it for like 2 weeks, but I read on here that if I miss payments, then it will eventually deactivate my account. I have a vanilla card and am thinking about switching my payment data to that so once it runs out it just doesn't work anymore and doesnt mess with my bank. Is this a good way to get out of paying for a service I do not want or will use? This account is under my school email so will that mess up my school account if the payment is done via a personal account with the same email? I really just wanted the free trial for a summer study abroad course but thats already passed because I forgot to cancel it. Adobe really does have predatory pricing practices and it sucks for such a titan in the industry to be this money hungry 😕😕
