Trying to login into Meino2 and cant reach customer services

Earlier this week I got in contact with o2 about changing the contact phone number registered on my MeinO2 account (my dutch phonenumber got forced into a german one by the registration system) because at the time I was checking my account info in regards to my land-line order. But around the same time that I received an email that my land-line request needed a phone adress I have been unable to login and/or unable to reach the English customer services hotline about either of the problems (either get disconnected immediately or told that number is no longer in operation).

Now luckily the wrong phone number thing has been resolved through the help of the community here (I assume because I CANT CHECK MY ACCOUNT) but after getting told to call the hotline to further progress my order I am stuck, because I cant login to see what step I need to take to finalize my router order and I cant call customer support to either help me login or to ask for order confirmation.

Has anyone experienced similar problems?
