Register Netflix when moving to another country?

I lived in Belgium for a few months and bought Netflix there. It is a euro or two cheaper there, the offer is a bit different (some programs are not in German). Now I'm back in Germany and would also like to pay the German Tarfi and have the local offer.

How and where can I change this? Or would I have to delete my account and create a completely new account?

I read everywhere that you always have the offer of the country you are in. But this is not the case! Both here and in Belgium I have the Belgian program and I don't use a VPN either. My family, who shared my account and lived in Germany, always had the Belgian offer.

I think that only writing to support or opening a new account will help

I don't think you need that, it will be automatic… However, you have to change the language + write to support, they will definitely help.
