I got charged twice by SLYNUMBER, what steps fix duplicate billing issues?

Double charges with SLYNUMBER usually happen due to duplicate subscriptions, payment retries, or system glitches, so the first step is to confirm whether both charges are actually for the same plan.

Check your receipts and account billing history to see if you accidentally activated two plans or if the system retried a failed payment.

Next, contact SLYNUMBER support again and clearly state “duplicate charge – request refund,” including both transaction IDs and screenshots, because companies can fix billing errors but often need exact proof to process refunds. Keep all emails and follow up regularly since responses may be slow.

If they don’t respond or refuse, please feel free to share your experience. You can also file a complaint on our website.
