Made A Tiktok For A Marketing Agency, We Agreed On A Price In Instagram Dms And Then They Ghosted Me. Is There Anything I Can Do?

A marketing agency messaged me on Instagram asking me to make a video with their artist’s “sound”. I’ve done this for them 5 times before and have successfully gotten paid. We agreed on a price ($150) and then I created the video. It was approved and they told me to post it, then they asked for my PayPal information as usual.

That was last week, they have since totally ghosted me. I tried emailing their public email as well, but haven’t gotten any payment or response. There was no formal contract, just Instagram DMs. Am I just screwed? Should I delete the video I posted?
