Reset my iTunes ID..

This is a user to user forum NOT Apple support

If you owned from new

then see here

If you forgot your Apple ID password

Have you owned the iPhone from new and are the only owner from new or was it second hand when you purchased from STC Saudi ????

There is no Apple support in Saudi, all issues are referred to the carrier

Have a play around here there might be something to try

http://www.apple.com/sa/support/

after updating, can you still open the phone? If you can go to setting>icloud>account, click on the arrow and change the icloud id. If not you can call apple support and request that the apple id associated with it be remove. Be warned, you need to pass the security check they will Require you to do. They might also ask you to send them a copy of your receipt as proof of purchase.

Correct me if i am wrong, 1 you are stuck in the activation process that is why you cannot go to setting and 2 you cannot remember your password nor the answer to the security questions. If this is true, call the apple support in your local site, tell them your issue and they will ask you with your birthday and credit card number associated with the apple id that you used previously on the phone. If you can answer them correctly, they will rest your password and you can use the phone again. In US this is the link we are using to get connected with apple. Choose your device, your issue and the method of contact you like. Chat or call is the best

As for your proof or ownership which is your receipt, you need to go to the store where you purchase it to be verified and ask them to call apple. Is it an apple authorized retailer or a third party? If it is an authorize retailer, they will obliged with your request, if third party, that will be a problem
