NUFIC Keeps taking money out of my checking acct. after canceling. New York New York

I took insurance out with this company and cancelled it almost a year ago and they're still taking the money out of my checking account. I didn't realize they were still taking it out because my husband balances the checking acct. and he didn't realize I had cancelled it. I never did get any benefits from it. I'm hopping mad because this is nothing but a big rip off company taking advantage of people. They should have their license suspended until they straighten their company out or taken away completely so they can't do business like this anymore.
