Extend exit re-entry visa

Hi All

I am out of KSA on an exit visa as my husbands dependant but due to unforseen circumstances could not re-enter in the stipulated time. The visa has now expired. Please can someone advise me on the procedure to extend the visa as my iqama is still valid. Some say my husband needs to apply in saudi first and some say it can just be done by visiting the saudi embassy in the home country. Please help! Also how long can the visa be extended for?
