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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
