How to cancel Sparklight by mail
Gather your account details
Check the account number, the phone number or service address being cancelled and the name on the account before anything else. A request that does not match the account on file at Sparklight is the easiest one to set aside.
Set out the request
Postbye turns the request into a finished English letter headed “Subject: Subscription termination – Sparklight”: close the Sparklight account, stop every charge and reply in writing.
Mail the letter with a receipt
Mail the letter by certified mail to the Phoenix address in the next section, and keep the tracking number.
Keep proof the letter arrived
Once the letter is delivered, the date on the receipt is the date Sparklight was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.

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.
