I've contacted Apple Support many times and I don't understand why my Apple ID is disabled

Try  contacting iTunes Support and if you don't get any assistance from the first person you talk to, politely ask to speak to level 2 support. Either use the form or scroll to the bottom of the page in the 2nd link. Follow through the screens to get a chat or telephone option.

Call Customer Relations 800-767-2775

Perhaps, Customer Relations are whom to speak with. Be polite about it, as mentioned above. Perhaps, they are whom to speak with.

"i've send a very polite email to itunes store support, they asked me to contact account security team so they can verify my identity, Do you think it will help ?"

Yes. I think it will help. Account Security Team seems to be just whom you need to speak with. Request a prompt for screensharing on your iPhone, and show them this screen. Use speaker phone while they point things out to you, and ask them where to proceed from there :)

It might. Given what you have been through already, if they can verify your identity, maybe they will finally attempt to help.
