Banfield Pet Hospital review: Wellness care plan

When I went to Banfield vet clinic in Clovis, Ca. for a vaccine for my dogs, I asked how much the shots for both dogs are, the front desk clerk hesitated to give the exact total, but then goes to tell me if I join their wellness care plan that I would save a lot of money for future vaccines as well. I mention to her I do not want to join any subscriptions plans for my dogs I just need the vaccines, but then she said my dogs can't be seen without the subscription, but the good news was that I can cancel at any time. So I agreed to join the plan for both of my dogs. My dogs get seen I pay $250 for each or so plus tax. I confirm with the clerk, so I paid for the vaccines and for their visit and that I can cancel at any time! she says yes then highlights what site I can go to cancel. So the next I month go to cancel my subscriptions but run into a problem saying I can't cancel until I pay what I owe. At this point I'm confused and angery because of how long it's taking to cancel this subscription. I end up calling the vet office to explain what I wanted to do then the vet tells me I can't cancel until I pay what I owe. I let her know I pay for everything I got the same day they were seen; she states that I owe x amount of because the screen exams are so expensive, so they broke it down into the subscription. I am so upset because I made sure I had paid for everything I got for my dogs that day because I hate hidden fees, nonetheless I'm still getting charged till this day, but I can't afford paying for their mistakes of not knowing or for them purposely bathing the customers for their own selfish gain.
