Netflix

I am more then furious, netflix has billed me twice in one month, when I noticed it I contacted them and spoke to the agent, the agent told me some **** about it being protocol to check if the account is still active (which makes no sense because I paid on the 4th so why am I paying again on the 11th? And of the same month?) So he tells me if the money wasn't refused immediately it would take 1-10 days from the day it was taken...

All these days pass and still no refund, I check them again and another agent tells me the same thing but now says in 30 days there will be a refund, it's beeen more then 30 days, heck it's even a new year and still no refund from netflix this will be my 2nd payment after the double payment and I just feel it's wrong, we're cancelling our subscription. I kept all the bank statements and screenshots from agents talks as proof but still no refund . I know it's just R199 but it's my money and I want it!
