Having called Xbox support, twittered to @MicrosoftHelps and posted questions to Windows Live support, I keep getting sent to someone else within Microsoft to fix the following problem:

When I go to https://commerce.microsoft.com, the dropdown in the blue banner topright shows three accounts:

BE - Personal Account (BE - Persoonlijk account)

NL - Personal Account (NL - Persoonlijk account) and

NL - Business Account (NL - Zakelijk account)

Windows Phone Store was in French, Xbox Music and Xbox Video on Windows 8.1 will give me music options and trailers in French, even though the text - e.g. the movie synopsis in the Video app - is in Dutch.

I'm Dutch, born here, live in Amsterdam and don't speak French!

Please remove completely the BE part of my account.

I'm sorry that I really don't get who within Microsoft is responsible and whether I post to the right Category/Product combination here. I just want to get this fixed - it'd be so much easier if Microsoft would take responsibility for this problem and come back with a solution instead of asking whether I posted here or there and whether I tried that support website or the other...

It's a fundamental setting in my account and strongly related to payment options (they're different depending on which of the three accounts I select) but the SYMPTOMS are visible in Windows 8 Video, Music apps and Windows Phone 8 Store, previously also in Zune. Now I care about those symptoms, but at the end of the day I simply want to get rid of that silly dropdown - or at least with the item containing reference to BE in it.

Thanks,

Eric
