I asked them the reason for that ..they said it's because medical fitness is not up to the mark. Medical Reason For Disembarkation : MDD (Major Depressive Disorder) On jan 2021 ...manning agent told me to do the psycho - Diagnosis from the authorized medical center. Upon request from the medical center I did the test and got the result as fit for duty.. I have included the test result and medical center letter to your notice.
