Cancelling a insurance or protection plan
Insurers cancel by policy and by effective date, so the request has to name the policy number and the date cover should stop, ideally after replacement cover is in place.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
