Audio Visual Services review: I worked for them and didn't get paid.

I worked on an audio visual contract for Audio Visual Services of Rhode Island from December 3rd to December 7th of 2023 in Concord, NC. I invoiced them for my work after completion, waited the 30 days as it was net30 and never got paid. It's been more than 60 days now and I've tried contacting them numerous times and they've never responded to my emails or voicemails.
