Long story short,
We cancelled a US Netflix account in Aug 2016. We have the confirmation email that they did this. They then continued to charge our Credit Card. We also have an NZ account so didn't see the charges still be charged to our CC. Yes, I know, we should check our statements better.
Anyway, we chatted online with them and they said all they could do was give us 3 months back and to contact our CC issuer. We talked with the CC issuer and they said it was up to Netflix.
Back to Netflix chat, same story but they said they could give us a further 3 months back and to contact our CC issuer.
We ask for an email address of the most Senior Customer Service person and were told they don't have that information to give out.
We then called the 0800 number on the website. Asked for the email address again and were told to send a letter and all supporting documents via snail mail to their corporate office in the US.
Told that for security purposes they can't give out email addresses.
WTf, it's 2019.
So we can't get our money back without jumping through hoops !!
