Friend takes advantage of me, how should I get revenge?

Idk why it wont let me post the full story so here it is: Last year I became good friends with one of my classmates. We were good friends. For example, he got in a fight with the other friends (while i wasnt there) in this post and I was there to fix the mess and just let him vent. So, we were good friends until this year because he has started saying rude things right to my face and expecting me to help him with things. Also he only says sorry when my other friends in our group tell him off or when he does something thinking I won't find out. For example, he said to hop on fort in a insta gc and so i joined the vc but my insta wouldnt let me talk. I joined 10 mins into the game so I waited for them to reset the game. Thing is when they restarted it I got glitched out so I wasn't in when it started. I asked them to restart it again less than 10 seconds into the game. 20 mins go by and they think I left the call but I was just there waiting for them to reset and asking ingame chat. 35 mins in I ask again and they say nope in the vc and start laughing (thinking I couldn't hear the call). 40 mins in I quit the creative and stay in the lobby. 45 mins in the whole party left the creative and right away the friend im talking about says "I'm sorry [blank] u need to leave" so I leave and they start laughing in the call until one of my friends who wasnt told them I was in the call. That's when he apologized and he was laughing while saying it like he didnt just waste 45mins of my life smh. So I'd like to get revenge on him.
