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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
AT&T Wireless lets you cancel directly (phone). A letter is the fallback that leaves a dated record when the direct route fails.
