Open Question: how do i cancel titan insurance?

i was speaking to a titan insurance rep and he said, to cancel, just stop paying for it and they won't bill you? im assuming once you stop paying for the premium they'll just cancel the coverage?? cause i believe if you called in to cancel they'll tell you, you'll have to pay for the months' premium and have proof since it was a recorded.. correct me if im wrong but i did get a bill for $5xx.xx but i dont want the premium anymore. its too expensive and i found a different well known insurance company that has lower rates.
