Dear Microsoft,

No offence but there's no clear option to be able to choose the account language and to be consistent across all platforms and applications.

HOW CAN I CHANGE TO ENGLISH AND HAVE IT SET FOR GOOD WITHOUT CHANGING BY IT SELF BASED ON THE OTHER REGIONAL SETTINGS???????????????????

BELIEVE ME, IT IS RELY ANNOYING!!!!!

Best regards,

George

I have been locked out of my hotmail account. My account is (*** Email address is removed for privacy ***). 

It says it appears that someone else is using my account so I needed to verify my account. However, I have tried to provide the information required as best as I can remember but I have received an email saying "we were unable to verify your ownership of this account using the information you provided". I can submit another form but I must just not know enough information. It is very important that I get back into this account. 

Is there any alternative ways of contacting someone at Microsoft to find out how to get this resolved? This really is an urgent matter.

Thank you!
