Cancelling a health or wellness subscription
Health and wellness plans combine a monthly fee with supplies or consultations, so the request should say what to stop: the plan, pending shipments or both.
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.
