Dear all, as my previous message that i dont receive any email for temporary password. So last night, i made another phone call to Yahoo Customer service (CS).
After a bit explanation & i gave the ref no. for the previous call i 've made, then the CS girl generate the temporary password in their system. After that she tell me on the spot the temp password.
And this morning , using the temp password that she provided to me last night .. so at last i can log in back to my Yahoo Account. Thank God.
