I can´t change the region for my Apple ID because of cents in my account and hence I cant activate my new iphone.

Hello,

I see you have remaining balance that you wish to remove from your Apple Account. In Apple's support article Change your Apple ID country or region - Apple Support Apple lists only a single way to do this:

"If you still can't change your country or region, or you have less store credit than the cost of a single item, contact Apple Support". Apple offers this specific link for that service --> https://getsupport.apple.com/?caller=kbase&PGF=PGF63005&category_id=SC0998&symptom_id=20198

Apple will remove the balance and keep it.

Or, as Recommended by Apple in this thread Apple ID balance - Apple Community , tap or click here ➞ Official Apple Support . You may find, however, that it is a lot faster and easier to use the link in the previous paragraph since it is the one provided by Apple itself for this situation to directly take you to the people who can help you with this.

It would help if you had said why you cannot contact Apple. If it is a matter of them not answering the phone then keep on trying until you find a day of the week and time of the day that they do.

Make sure you look through the countries list including "other" categories in each region listing. Not all countries have their own contact method.

Choose your country or region - Official Apple Support

Choose your country. Some may have different languages available. If your country is not listed see if there is an "other" option for your region of the world. E.g.,

Other Africa - Official Apple Support

Other Middle East - Official Apple Support

Other Asia - Official Apple Support

Other Europe - Official Apple Support

Latin America and the Caribbean - Official Apple Support

If your country is not listed on the support pages, go to this web page and fill out the form:

Media Services - Contact Us - Official Apple Support

Did you try this number? 0800 048 0408.

What about this link to Iceland Support? --> Official Apple Support

I can't experiment with it for you because my account setting mean I keep on getting redirected to USA support. See if you can find some issue, any issue, that ends up with a chat or telephone call. Then ask the person to redirect you.

In what country are you located? That form link works anywhere in the world I believe.

Can you get a chat or telephone call to any kind of Apple Support? If yes then ask to be redirected.
