Property Management problem, advice needed.

[Shuai Zeng]

Hi All, been a while since I been here. I need advice on this property from you guys. 

Property was least half of the year, until Dec last year. Tenant had to move out early, so bailed on deposit. Management took 1 week to get to email me on status update on this, then took 3 week to get them clean & and rent it out a month later in Feb. New tenant move in, was screed by management. They only paid first month of rent & deposit, decided they don't want to pay anymore. Took 1 month of time of threaten by management to get them out, and half month to get it clean again. Was told by management they won't charge first month 75% fee from new tenants due to their previously fault. Property then sit for another month and finally rented out 2 weeks ago. I emailed the management, regarding the payment for new tenants. So after a week later, I email again, and call couple times. Did not reply me & did not answer when I called. 

Can you guys advice on what my next step should be?
