You call them screaming like I just did or you report fraud to your bank.

Yes, i just enrolled in the one year membership and cancelled all of my " credit and debit cards " still active on my account. They can't charge anything if your
' saved ' credit and debit cards are " deleted '. Since I do get prescription meds for my dogs on their site and I just joined, I'm keeping it for one year but they can't renew it if no cards are saved.

You have to call the 800 number listed on the site,. Be prepared to argue with the CSR. They don't care whether you want a refund or not. They will try to get you to purchase something else then leave snarky comments about you on your profile.
