AITA for not putting my classamet's names in the powerpoint?

TW: English may not be perfect

Here is some context: I have to do a PowerPoint for 8th grade science about male reproductive system, and i got paired up with 3 other boys. We All procastinated to the Last day (today), and i Messaged them on when we Are going to do It. I proposed that if they send me materials i can build it, but they ignored me (im not close with them btw). This Morning, i did the project myself, researching the stuff myself and just doing the powerpoint myself. At the End, i didint put their names because they didint help me, but they started to insult me, calling me unfair, arrogant and selfish. Now the project is due tomorrow, and i dont know what to do.

Mini update: the assignment got moved to 11th of February, so i still have time

Mini update 2: they agreed to help me, i feel like i just found a 4 leafed clover lmao
