Skimlinks owe us $6k affiliate revenue and hasn't wire a cent in 2 years

Background: Run a social network. Been using skimlinks for outgoing links as another source of revenue

My bad: Should have noticed monthly payment stopped since 2018. A code refactor brought the issue to surface.

Their bad: We sent multiple support emails over the last three months. Even private messaged their CEO and official account on Twitter. CEO didn't respond. Official twitter gave us their standard response - "we are looking into it".

I am running out of options here. Should I file a small court claim? 6k is the ballpark amount shown on their own dashboard for payment history and affiliate cut. To their credit they did not delete those data. So the account keeps accruing revenue with no avenue to withdraw.
