Q: Verifying account on app store

Hello guys

I have a lebanese account on the app store, i added a payment method ( pic card) 1 year ago and it's not valid anymore

Now, a message appears asking me to verify my payment infos when i request to update an app and i don't have a payment method anymore

Note that there is not the 'none' option under payment type and didn't find any solution online

Hope you guys can help me

note that i'm using an iphone5 running ios8.0.2

thank you so much for any help
