Why did my new job do this to me?

I live on my own.. and I had a job before paying my rent and everything to live. Worked there for 3 years. I decided to get a job at GARDA because I was offered it, I had to quit because they PRESSURED ME TO QUIT, saying you need to quit dont worry you got a job with us now ! First two weeks of training are not paid. 19$ an hour to work at the airport.. anyway the day before class I found out the exam was extremely hard. So I asked the teacher what happens if I fail the exam?! Because I quit my other job now and have bills to pay. He told me do not worry you are always gonna work in Garda , you will just be security at a different post somewhere else besides the airport If I fail the airport exam.

1 week in .. I fail my first exam as it was extremely difficult.. the teacher tells me that im sorry you have failed.. but I have sent the information to the person in HR who took you. Your file is being handled with them now.

So when i got home later that day I emailed the guy handling my file and said I understand that I will be working at a different area, may I have the details of where it is and when I can start? And he sends me back in email saying “im gonna look into it” THAN! Sends me an email right after saying I found you a patrol site! Im gonna get you an interview with the officer. I emailed him back saying thats great, when will the interview be? No reply. I send another email 2 days later. nothing it almost been two weeks now, and I left a voicemail Friday, nothing
