Hey man, I feel you, but this is not the way. The best way is to tell your prof and get your mark raised (or theirs lowered). Shred them during peer review if you can - if peer review isn’t available, ask your prof to offer the option and tell them why you need to submit a peer review. It helps to have screenshots of texts/emails from you asking your groupmates to get shit done, and it also helps to have everything on google docs so you can hand in the version history to show their exact contributions.

If the prof is unsympathetic to the above efforts, you can try going to the department head. I don’t know much about this process since I haven’t done it myself - most profs are sympathetic to keeners who make a case against their toilet leech peers.

Unfortunately since this has been developing for some time, you probably don’t have a choice except to get the project done yourself. It’s likely too late to assign you to a different group, or give you a modified assignment to do on your own. I would have raised this issue in the first 3 weeks if not earlier. Good lesson for future reference!
