COMMON MISTAKES

Avoid these before you start

Do not delete the app and assume billing stops

For Quantum Fiber, use the cancellation route shown here. App deletion, logout, or account deletion can leave the paid subscription active.

Check the company that actually bills you

Match the cancellation route to the name on your receipt, card statement, or account page.

Separate service cancellation from equipment or number transfer

For Quantum Fiber, a disconnect request may not finish the job. Confirm any phone-number transfer, device balance, modem/router return and final statement separately.

Save proof before closing the page

Keep disconnect confirmation, billing date, equipment serial list until the next statement shows billing stopped.

IF THIS SOUNDS LIKE YOU

These are the side issues that most often confuse a Quantum Fiber cancellation.
