It's 25 years since I had anything to do with the Buckinghamshire Probation Service (as I think it was back then). I used to look after their computers. But they absolutely wanted people off the criminal circuit. And they were hugely over-worked.
You should write to the head of the probation department expressing your concerns. Your calls with the probation officer are recorded, aren't they? Don't be defiant, don't explicitly complain, just say you don't understand why X, Y, and Z are necessary and they feel unnecessarily intrusive. Probation officers are human.
