Can car insurance company drop you without notice in the state of Florida?

I was insured with State farm back in october. My driving record is not perfect by any means. (No At Fault accidents, but some moving violations). I found out that i was dropped after checking my bank statement that i recieved a large deposit from the insurance company. I called them up and the told me that i was dropped. So in part i was unknowingly driving without insurance. Statefarm calls me today 12/31 out of the blue, saying that they've tried sending me the notice and wants to confirm my address and to return the document with my signature.
