Netflix Overcharge

I recently noticed that I have been getting overcharged by Netflix by R80 and they say it is because I used a VPN which I have never.

I currently pay R249 for a Premium bundle, which actually costs R169. When I queried this, I was told that I use a VPN or Proxy and I'm being charged in Euro's. When I have never used any VPN or Proxy.

For two years I have been getting overcharged by at least R80 because they moved my membership from South Africa to America to Europe without my authorisation. And all they did was change my country but have still kept the money they overcharged me
