Would itbe over dramatic to call the cops on this cab driver?

I accidentally left my house keys in his car on Saturday morning. Hhasn'tnt been returning any of my calls. He finally called me back today and apologized and explained he works to jobs and is very busy. He said he gets out of work at 8 and will drop them off once he gets out. It is now 912 and he is ignored me when I called at 830. I just sent him a text. I dont know him and am worried he could of made copies of my keys. My city isnt the safest (i live in upstate ny) SHould I jsut call the police? I called the main taxi place and they said there is nothing they can do
