Firing my Property Management Company

[Paddy Krishna]

We bought a property in Baltimore from a turnkey operator. The turnkey operator recommended a property management company. The property was rented  a tenant. After two months the tenants stopped paying the rents. The property management didn't even know that the tenants were paying rent until we complained it to them. It has been 5 months since the tenants paid the rent. The management company has done nothing to collect the rent nor reached out to the tenant to make alternate arrangements. They don't return our calls nor respond to our emails. 

We later came to know, almost all the investors bought property from the turnkey operator were using the same Management company and they all have bigger complaints than us. The irony is that no legal actions were taken against the management company and they are still in business. 

We want to move to a different property management company. We emailed them saying our intention to move to a different company. We requested to send a copy of the ledger. But they are not responding to our calls and we are are at a loss. 

My question first questions is what is the process to fire them and move to a new management company? Second question, if at all possible, how to collect the unpaid rents from the tenant?
