Have you submitted your invoices? You won't get paid if you have not submitted invoices in accordance with Cirrus' policies. (They have a special form to send out and email to email@example.com.) If you have done so, I suggest that you submit them again and cc Monnie Howard (the owner) at firstname.lastname@example.org. I have had to chase payment several times for them, but have always had an immediate response from Monnie when I have emailed her.
Note, as mentioned above, they do have very slow pay schedule - the slowest I have seen in the industry. As of last week folks should have been paid for their September 2018 shops.
Hard work builds character and homework is good for your soul.
