Netflix complaint: Netflix is not an honorable company. Does anyone care? I do!

I am a busy teacher and mom. I look for large amounts when I receive my credit card statement. I also look at familiar names. So when I discovered that Netflix had been charging me twice for over a year and a half. I was surprised that they had done this under the radar for so long. I thought certainly Netflix would have decent customer service and credit my account for future Netflix use. Especially, I have been a Netflix customer for years.
That was far from the truth. I spoke to Netflix Jim who emphatically told me that he nor Netflix was responsible for double billing. The best Jim could do was credit me back one month of double billing. He suggested that I call my bank and file a dispute. My bank said that since Netflix admitted to double billing; I was not eligible to dispute Netflix for stealing. Thus, I am canceling Netflix. I have a couple of friends who are also appalled. Shame on you Netflix.
