If your provider charges you for equipment you returned, match the charge to the specific device and collect the drop-off receipt, return authorization and tracking record. Ask the provider to reconcile those records with its equipment inventory and billing entry. A delivery scan and an account adjustment are different records.
Identify exactly what the charge covers
Check whether the disputed item is an unreturned-device charge, ongoing rental charge, damaged-device charge or another equipment-related fee. Ask for the device identifier, service address and account period associated with it.
A household may have replaced several devices over time. Match the identifier shown in your return record with the device the provider says is missing. Do not assume that returning one item resolves a charge for a different item.
| Record | Details to compare |
|---|---|
| Charge or inventory entry | Device identifier, amount and account |
| Return authorization | Selected device and permitted return method |
| Drop-off receipt | Return date, receipt reference and any listed identifiers |
| Tracking record | Shipment identifier and delivery status |
| Provider acknowledgment | Date received or recorded, and any promised adjustment |
Gather the strongest available return evidence
Use these checkboxes while you work. Selections are not saved when you leave this page.
Keep the originals and submit relevant copies through the verified support process. If your receipt lacks an identifier, say so and ask whether the provider can match its receipt reference or tracking number to your account.
Check your provider’s current return instructions
Look for the instructions for that device, not just a general cancellation page. Confirm where the equipment should have been returned and whether your method followed those instructions. If the provider says a processing period is still running, ask which published instructions apply and when to follow up.
As one provider-specific example, Xfinity’s return guidance tells customers to match device serial numbers and retain return or tracking records. Its device exceptions and return options should not be generalized to other providers.

Ask for an inventory and billing review
A return exists, but the account still shows a fee
“My bill shows a charge for device [identifier]. I returned it using your authorized process on [date]. The attached receipt and tracking record show [what those records actually confirm]. Please compare these records with your equipment inventory, explain the remaining charge and correct the bill if the device was recorded incorrectly.”
Ask for a case number and a written answer. If the records name different devices, ask the provider to explain the mismatch. If you do not have a receipt, request a search of the return records and be clear about what evidence is missing.
Use the complaint letter template for the complete message.
If the charge remains unresolved
Request the provider’s explanation of why your documents do not resolve the charge. Then review the FCC informal complaint process for a relevant telecom billing issue. Include the charge, return evidence and provider response in your complaint.
Not every complaint is served on a provider, and a served complaint does not guarantee a credit. The FCC describes different treatment depending on the issue and can refer matters elsewhere.

Confirm the correction in the account
If the provider agrees to a correction, ask whether it changes the equipment inventory, the fee, ongoing rental charges or more than one item. Save the answer and check the subsequent statement.
Keep return records after the initial drop-off. A scan showing delivery can support your account, but it does not by itself show that the provider matched the item to the right account or posted the expected credit.
Common questions
What if I lost the return receipt?
Look for the return email, shipping history, account message or a duplicate receipt from the location. Ask the provider to search its return records using the information you have. Do not invent a confirmation.
Does delivery tracking guarantee the charge will disappear?
No. Ask the provider to match the shipment and device to the account, then confirm the billing adjustment.
Can I use another provider’s return deadline?
No. Check the instructions applicable to your own provider, device and transaction.
