My immigration case was closed for abandonment.My lawyer did not send my RFE to USCIS, neither he followed up on my case for 13 months.

I hired this law firm for adjustment of status. USCIS requested a medical examination and my lawyer did not send it when I delivered into his office. After 13 months, USCIS send ,me a letter denying my case due to "abandonment". Lawyer provided an online printed shipping label but shipping was never send. Neither he double checked on the status of my case or did a case inquiry. After I questioned the law firm, they stated that I had to pay like a new case again since my case was denied. Law firm asked for another $3,600, which I said it was their responsibility and duties as lawyer. they responded with a case close letter. and later the lawyer called me and yelled at me over the phone. I subject a formal complaint to the California State Bar (They just assigned an investigator for my cae) and to the Immigration Counsel, they send a received letter. I am strugg a lot since the letter says im subjet to deportation after 33 days of the letter. At this point I feel very ansious about it
