EHarmony Fraud...Can you fight them?

[Curious Fat Guy]

Back in 2012 I signed up and paid for a membership to EHarmony. I chose a short term plan. I turned off the automatic-renewal option immediately and after a few months I decided to close the account. After closing it I then took some type of survey where they ask you why you closed your account.
Fast forward to this month when I notice a charge from EHarmony on my credit card statement. I usually just pay off my card so I rarely check the statement. I called customer service for my credit card and they tell me that I have been getting charged every month since May. They have charged me over $180.
EHarmony claims they did nothing wrong and that they owe me nothing, but would be happy to stop further payments. This is obviously fraud and I want to know if I have any options.
