Lawyer Cashed Retainer Check And Then Ghosted.

I’m having issues with an old landlord, so reached out to a lawyer that was recommended to me. I’m out of the state now, so we talked on the phone. He said he would go over my info and advise, said it would take about 3 hours @ 250$ an hour. I overnighted him a check and my documents. We spoke once since , about an additional document I wanted to send. My check was cashed. A couple days went by with no contact. I started calling and leaving messages with no answer or return call. I called his office from a different area code 3 days ago, a secretary answered and said “just one minute” when I asked for him, but was then hung up on. It’s been 8 days since he cashed the check and 8 days since I’ve been able to talk to him. The landlords deadline for response was 4 days ago. I don’t know what to do, any advise would be greatly appreciated.
