Who would I talk to, to see if he can get a bond for a probation violation?

He was sentenced to 90 days in jail for not having his fine payed on time, he is on probation, I just don't understand why he didn't get a bond? I talked to his lawyer he said he doesn't represent him anymore, called the circuit courts office, she said he represents himself now. So I was gonna try to see if he would be able to get a bond or not. Who would I talk to, to see if he can get a bond? I called his probation officer, and left a message.
