Cancelling a phone or internet plan
Phone and internet providers tie cancellation to contracts, equipment balances and notice periods, so the request should name the exact line or service and ask for a final bill in writing.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
