Medi-Cal help Fresno County

Hey so Im currently trying to get my Medi-Cal renewed here in Fresno County. While renewing it my application says incomplete cause i need a sworn statement of no income. However im trying to get in contact with a case worker but every time I call it just says all agents are busy hang up. Has anyone ran into this issue of not being able to reach them. Any advice on how to get a hold of them? I did upload the sworn statement but no response. Should i try mailing it in?
