Property Manager failed to pay property owner rental checks

[Emily Chen]

My property manage company started to have late checks, bounced checks, and miss paying checks since 2018. Now I changed property manager. I called and emailed, the owner never reply. The property manager said she collect rent from tenant but she does not issue the check. I have never seen this type of property management before. How do I get the missed payments back (last 3 month rent)? Please advise. Thanks!
