because your support is unsatisfying
It's not our support, we are just fellow users and these are user forums, you're not talking to iTunes Support nor Apple on here.
If you've forgotten your answers to your security questions, see if you can reset them : If you forgot the answers to your Apple ID security questions
If you can’t reset them yourself contact Support in the country where you are (and which is therefore the country on your account) and see if they can reset them for you : Contact Apple for help with Apple ID account security
If your country isn't on that page try this form to contact Support : https://www.apple.com/emea/support/itunes/contact.html
