I have been trying to get them to stop charging my account. There is no way to do that online, and I have no need for the account any more. I sent them an email requesting the cancelation, but I have sent them many emails, and they never respond. They have horrible service, but I don't believe they are the worst place to advertise your pup at. I am a breeder, and I have gotten many responses from here. Even a place such as KIJIJI, or Craigs List, has better service and membership options.
If you have problems with billing I would recommend you cancel all your credit card payments from puppy find, by asking you credit card company to do so. I want to keep advertising there, because it does bring in business, but now that I can not cancel my account, the 20 dollars has turned into over 90 dollars in payments.
