Good news! I did only one signing for this company back in 2016. They took 4 months to pay. Here is what I did. This will work for both of you as well.
Bring up the original order and get a hold of the Title officer at the title company, notify them that you have not been paid for that signing and have them put pressure on THE WORST NOTARY COMPANY, to get you paid. Have them cc you on the email to get you the signing & title company communication on the same email until you receive your check.
This works for me EVERYTIME.
