what do i do? house commisioner is being rude

i'm doing a house and furniture pack commision on tiktok for someone who is only giving me 30 value which i didnt think was that much, but i still accepted the offer because i thought it would be fun to make a minion house and furniture + plushie pack. but theyve been rushing me for a week to start, and then they told me i had to finish in a day and they were threatening me with something that i'd rather not say here. then they were telling me i had to make gru which they never mentioned before and i told them that i couldnt because i've never made a human character and i thought it would be hard, now their pressring and threatening me also kept staying in the server to "watch me build" which kinda made me uncomfortable so idk what to do because of the thing they were threatening me about
