Nevada Asset Preservation & Management

I own two homes which they are managing and I am blown away by their lack of efficiency. One home took 3 months for them to find a tenant to lease it to. I started to think that maybe they made a mistake and didn’t list the property. I found that it was on the Multiple but not advertised on any website. Most people do not contact a broker to lease a home, they look online.
I should also mention that they had me sign the lease for the full price that I had requested and then told me that they forgot to tell me that the tenant was told that I would take less. I feel that they are not on my side but the tenants.
I did not want the same thing to happen when my second home became vacant. I went online and advertised it on Zillow, Trulia and Hot Pads. I have received several phone calls and emails in the last two days. I gave everyone the telephone number of the Management company to set up an appointment since I live in another state. It is ridiculous that I have to find them prospective tenants.
The thing that really upsets me is that they do not take responsibility. I wrote an email explaining that I lost 3 months rent and should have some form of compensation. NO REPLY and NO APOLOGY.
