I use Privacy.com and generate virtual credit card numbers. I cancel the credit card at the time of canceling the service (or at least trying to cancel the service).
Won’t help if you breach contract and they go to collections
exactly. it is really interesting that service even exists. Canceling a privacy.com card does not magically cancel a contract. Privacy.com seems like a great way to trick people into tanking their credit ranking when they think they are getting back at a company for being hard to cancel.
