Need help! My channel might get terminated. Suggestions?

Both UMG and RIAA took down 2 of videos this month even though I have a right to use them. Therefore, I now have 2 copyright strikes. I have filed an appeal for both strikes. For one of them, YouTube said they'll make a final decision later this month if they do not hear from the claimant within the next 5 business days.

I am very nervous and frustrated now. Monetization might even get disabled on my channel again due to these unfixed system errors and companies abusing their powers. I've been generating well over $100 per day for myself and YouTube with my videos, and this is how they treat me?!!
I even make sure that I have required rights and permissions to use content before uploading them, so why is YouTube being a dick toward me?

I want to join a network now if it's not too late. What is the best MCN I can join? I mainly need a good MCN to help me effectively both dispute and prevent ridiculous copyright claims in a timely manner. I should NOT have to wait a month for a claim to be resolved.

I upload a lot of music. Should I join INDMusic?

Any suggestions? I urgently need answers in the next 10 hours. I have a feeling YouTube will shut my monetization off within the next 48 hours.
