Narrative: Today upon preflight we found the same maintenance write up from the day before still existed with just the batteries on. I called Maintenance and spoke with a Maintenance Controller who I verbally confirmed the AOG (Aircraft on Ground) with followed by the appropriate write-up which was exactly the same as the day before (Left T/R flashing) with battery power only visual inspection confirmed the TR (Thrust Reversers) was stowed. Approximately 20 minutes after the AOG was sent in I received a phone call from Maintenance Controller.He was rather annoyed in his tone with me. I explained to him the problem we had. Also that I questioned the Maintenance performed. They could not duplicate the problem and presumed the crew caused the problem by improperly moving a switch or improper sequence of the controls. This was stated in an email sent to us from [second] Maintenance Controller. This is absolutely false and wrong. The failure occurred upon power up yesterday batteries only. We landed and shut down with no problems. We have over 20 years of flying experience in the cockpit and it's insulting to the crew we were somehow responsible for his failure.That is not the end of the story. [Maintenance Controller 1] then rudely asked if we were on the plane and we were he then asked 'is the red TR switch still flashing?' I said yes it's still flashing. I also said we had a Maintenance page showing record of failures in the cockpit. The page showed the TR fault multiple times. Still rudely asked me to go up and push the Red TR button. I complied after informing him of the info already sent in. He said 'Just push the button tell me what you see' I complied as he was becoming very negative and hostile in his tone with me. After pushing the Red TR button he requested the button now remained solid RED. [Maintenance Controller] now rudely said 'Push the button again...tell me what you see?' I did as he instructed and pushed the solid Red TR button and it began flashing Red again and informed him of what it was doing. [Maintenance Controller] replied 'Great' and slammed the phone hanging up on me.I'd like to know why this kind of unprofessional behavior is accepted? Safety first. We did our jobs and were treated with a complete lack of respect. At no time was our reply or interaction with Maintenance out of line or unprofessional. That is not the case with [the Maintenance Controller]. I hope he will be sat down and spoken to appropriately about his behavior. This is not who were are and should not be tolerated. My Co-Pilot witness the entire phone call I had with [Maintenance Controller] as it was on speakerphone.
