While enroute IFR I was climbed to 6;000 feet. I was passed on to approach. Up to then my flight plan was RDU LIB NASCR 1 arrival to JQF. I was issued vectors to the south after 3-5 minutes. I asked how much longer I would be on this heading. They responded 20-30 miles? Then I said I'm canceling IFR and climbing to 6;500 feet and will be turning on course. Approach said climb to 6;500 feet and turn on course and remain clear of their airspace.After a few minutes they asked why I was not heading on course and I told them I was not going to do that because I turned on course to my destination. They didn't like that and said I had to listen to them. Their airspace only goes to 4;400 feet and I was at 6;500 feet. There were other words passed on between us then I was told to call a number upon landing so I did. This has happened above their airspace numerous times in the past by other pilots that I have heard on the radio. It has also happened to our company in the past and we have always canceled IFR and continued on our way with no issues. I always like to talk to the controllers for additional safety but after having this response from Approach I feel like never talking to them unless required because of low weather. This is not a safe thing while over flying any airspace and not talking.
