Harassment by 1life call centers

My policy has canceled due to none payment. It's not a loan, it was for insurance. No premium no cover. Yet 1life call center phones me between 10 and 18 times a day, even after business hours and on weekends. I have told several consultants to please make a note that I am not renewing the policy and for them to remove my number off their data base. I am still receiving calls till this very minute. This is now become harassment. If this continues I will be forced to lodge this at the ombudsman and the police. They call one after the other, none stop. No matter what I say or how I say it they keep on calling. My phone records are available to prove it.
