Narrative:

When I was at FL240 with ZOA, I requested FL220. I wanted to make a quick stop and then continue to my destination to pao. I idented the closest airport during my transition from FL240 to FL220. I requested to go lower than FL220 and then canceled my IFR to VFR plan. At this point, I believe my communication with ZOA was confused. Then I became defensive in my flying, looking for other aircraft, etc. Then ZOA gave me a telephone number to call them, and 3 mins later they gave me another phone number. When I called, the first thing he said to me was to give an explanation about my mistake during my flight. I realized that there was miscom. I would like to resolve this so that there is better communication between controllers and pilots. Callback conversation with reporter revealed the following information: this BE20 pilot requested and received clearance down to 17000 ft, and broadcast that he was cancelling IFR when he passed through FL180.
