I am formally disputing a billing discrepancy on my account [[REFERENCE]]. Invoice #INV-2023-105 dated October 5, 2023, includes a $29.99 charge for 'Premium Support,' which is invalid as I canceled this service on September 15, 2023. See attached cancellation confirmation.

I request immediate reversal of this charge, issuance of a corrected invoice, and written confirmation of the account adjustment within 7 business days.

Thank you for your prompt attention.

Best regards,

Subject: Escalation: Unresolved Overcharge on Billing [[REFERENCE]] – Action Required

[[NAME]],

Following my email on October 10, 2023, regarding the erroneous $29.99 charge on [[REFERENCE]], no correction has been made. This overcharge remains on my account.

I demand immediate refund of $29.99 and confirmation of account update by October 25, 2023. Failure to resolve this will compel me to escalate to your supervisor and file a complaint with consumer protection agencies.
