Write your request
The letter asks diamond Sports to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – diamond Sports”. Postbye fills it in from our English template.
Mail the letter with a receipt

Keep proof the letter arrived
The receipt dates your request. Look at your next statement for any diamond Sports charge after that date.

Before you cancel diamond Sports, check these
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
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.
