Can a Judge impose a sentence different than what he said in court without informing the defendant?

I don''t know if I asked the question properly given the complexity of the situation. I was on probation and violated by not reporting. I went to court a few times a ended up being sentenced to 10 days in county jail. When I was told this in court, I specifically asked the judge if that meant I would continue probation upon release from jail. He said no, I was doing the jail time instead of the probation, however I would still have to complete my community service upon release. That was 2 monthes ago, and yesterday I recieved a call saying I have to report to probation next week. I just want to know if there is any action I can take in this situation, given what I was told by the judge, and the court proceedings are audio recorded so there is proof of what he said.
