eHarmony complaint: Charged debit card without my authorization

During my subscription, I got a new bank debit card. My old card was closed. When I first started my subscription, I used my old card information for payments. When I got my new card, the old card was closed. On the 16th of August there was a charge on Bank account for $199.01 from eharmony. I was upset and confused. There should have been no way my account was charged because they did not have my new card information for payment and old card doesn’t work. I did not authorize this payment. I have been in email war with customer service and no one is answering my confusion about how they chaged my card without having the right information. Because of all this issue they now have overdrawn my bank account twice. I am not happy with their service. Since all this yes I have canceled my subscription and turned off auto pay. I will not ever use eharmony again or recommend them to anyone just because of this poor service.
