Narrative:

At gate in ZZZ; received maintenance release with numerous inbound write-ups including air data reference #1 inoperative. Troubleshooting led to an inoperative phc #1. Maintenance cleared adr #1 and deferred phc #1. I was unable to reach ZZZ maintenance on phone or radio; so I called maintenance control; spoke with mr X. He helped me understand the 3 inbound write-ups: 1) aft cargo heat fault; 2) adr #1 inoperative; 3) bscu #1 fault and the 2 deferrals -- center tank boost pump inoperative; and phc #1 inoperative. I asked for the MEL card. As I began to comply with the flight crew actions required by the MEL card; this led to more questions and I asked ZZZ line maintenance to come to the cockpit. Mechanic X and mechanic Y came and met me in the jetway. I asked them to go through the maintenance release item by item with me so I could understand the write-up and what actions they took to clear it. I asked them if all the maintenance actions were completed for the deferral of the phc #1? They said yes. I asked again; 'are you sure?
