I worked with the guy before and when I resigned, they made jest of me that I'll be poor and insulted me. Even to my customers.
You'll be wondering how I knew, I had a recording of their insults.

Yesterday he called me that I should lend him money and I asked him to give me a collateral.
Before you knew it the guy got angry.

Check our chat.
Did I do wrong?
