Addicting Games screwed me over

I created a small web-game that I sold to addicting games as a exclusive offer for a reasonable price. They game me an invoice to fill out that said payment due after 45 days. That was January 1st of 2024. Its been over a year now of asking and I still have not received anything. They invited me to their slack channel where I was talking to people who worked there and eventually they all stopped replying. I emailed their support page and they made it sound like I was going to get paid but they stopped responding as well.
It gets worse. Now when I go to contact their support its locked behind a login with no way to make an account. I have been reasonable and nice every time I have contacted them. Is there anything I can do? Did I do something wrong? Has anyone else had a problem with them?
Edit:
I tried to post the link to the contract but the post was removed when I did that. PM me if your able to read the contract and understand it more then me.
Also their Zendesk changed and I was able to contact them. Here is what they said:
"Dear Developers,

We are very preoccupied given the fires affecting our team and offices in Los Angeles.

The safety and evacuation of our employees is our utmost priority currently. We will provide an update soon on any outstanding payments and further exciting endeavors in the next coming weeks.
 
Kind regards,
Addicting Games"
