Unprofessional

I made an application 6 months ago online then I was told my documents are missing I need to send on watsapp I did so the guy who was supposed to help me was so unprofessional sending me messaging at nights telling me unprofessional things and when I did not pick up his calls at night he said he will not help me, I called the head office explained my problem and asked for help at first the ladies said that guy will not make such demands but gave me an email I sent the documents needed till this date ! The email I got Monday was I received ur emails n will process ur documents but today I hear something different !
