Netflix Netflix double charges Los Gatos Internet

I noticed on my bank statement that Netflix has been charging double for services. I started a chat with one of their representatives, and while chatting, I scrolled down my bank statement and noticed that they hadn't done this once or twice, but for 13 months. For 13 months Netflix has charged us two times each month. The withdrawals are usually around four days apart. I gave their representative my bank and card numbers and was told that they had no record of having double dipped for services and that I would have to give them my husbands information if I wanted a reimbursement. I gave them the last 4 digits of his card, but didn't feel that I needed to give them more than that. They should have a record of payments and where they come from. But they don't. Meanwhile, I'm looking at my bank statements and seeing two payments per month going to Netflix. I cancelled my service and will not be reimbursed. I'm speaking to a lawyer after the weekend.
