Narrative:

I filed my flight plan from ZZZ to ZZZ1 and received the xxxxx departure procedure. I tried to reach the ZZZ tower for clearance and they were still closed. Then I tried to reach ZZZ clearance delivery on xyz.za while on the ground; no answer. Since ZZZ was VMC conditions; I chose to take off and get my clearance in the air like I often do from my home airport ZZZ2. Once airborne and on my departure procedure with auto pilot; I reached xyz.za and was told to wait a minute. After a minute; I restated I am airborne and need clearance. I was told again to wait a minute. After a minute or so; I told xyz.za I was approaching ZZZ3 airspace and needed clearance. I received a squawk code and was told to wait; again. While waiting; I inadvertently continued into the airspace; unfortunately.once in the airspace I was asked to switch to approach frequency. Which I did immediately. Approach vectored me north out of the airspace; and asked if I received clearance from ZZZ. I told them I did not; but was in communication with ZZZ clearance delivery and told to wait. He told me I can't do that and gave me clearance to ZZZ1 and a phone number to call upon landing. Which I called immediately upon landing in ZZZ1 and explained my mistake to stay on the xxxxx departure procedure and wait on ATC; instead of doing a u-turn and remain clear of the airspace; then wait on ATC. On a side note; upon entering ZZZ4 airspace and requesting RNAV xx into ZZZ1; ATC had me descend to 3;000 in preparation to land RNAV xx at ZZZ4! I restated I need ZZZ1 as indicated in my flight plan and they had me immediately climb back up to 5;000. Then vectored me to the initial approach fix for RNAV xx ZZZ1 which I flew on autopilot without any further incident; landing safely and very happy to be on the ground.
