I can't seems to recover the security questions at all no matter what?!?

So i have been having this problem for a month now, & am still trying to solve it, the real problemn is that when i try to purchase an item it asks me to answer my sequirty questions which i forget what they were & i can't make any purchases, only able to download free contents, i have emailed apple support team, they told me to email the other person, then i recived an email from him/her

then he told me to call the Saudi arabia support page, & in that page it suggested that i send an email once again, which i have done actually anyway? so why again? i have asked from the person i have received email from is that it told me the same solution, after i received the answer from the email, i was told that i should call the Apple Secutrity team, which i tried anyway, but it doesn't seems to work

so now the only step i haven't done so far is calling the apple security team number, how can i call them from Saudi Arabia? since i'm from there? any solution? thanks

ps: yes my itunes store is US & i use an ipad 4 & iphone 4 s (i also lost the email from apple so i can't remember all the exact details)
