Crossroads — Repeated Calls in spite of clearing that service is not needed

I receive at least 2-3 calls per week from this road side assistance company called Crossroads. I had purchased their annual plan once and I started receiving calls 6 months after my purchase for renewal. On repeated requests that I will renew later, they still kept calling. I then clearly told them that I do not need the service and bought another service. They have been calling without fail since then and I have told them multiple time now that I do not need the service.

I would want to request strict action against them.
