T-Mobile post-port-out modem return dead-end keeps customers billed and at risk of $370 charge
After porting out, a customer cannot return their modem because the store rejects an expired DL while phone support requires a 6-digit PIN. Months of cancelled service still bill, and the customer faces a $370 unreturned-equipment fee through no action of their own.

surfaced semanticallyAT&T Repeatedly Fails to Zero Out Erroneous Bill After Multiple Confirmed Promises
A customer who canceled AT&T service within days due to poor signal quality was promised a zero balance multiple times over several weeks, yet kept receiving new bills, including a $141 charge for internet service they never activated and returned unopened. Consistent with a recurring pattern of billing reconciliation failures at AT&T where confirmed resolutions do not propagate to the actual account.
Telecom providers charging for service after cancellation and equipment return
Consumers who cancel telecom service and return equipment are still billed for months they never used. Reaching cancellation support is nearly impossible due to long hold times and busy phone lines. The gap between equipment return confirmation and billing system updates leaves customers liable for charges they should not owe.
T-Mobile Continued Billing After Equipment Return
T-Mobile continued charging for home internet two years after equipment was returned. Account authorization policy prevented cancellation.
Telecom Carriers Bill for Service After Port-Out Cancellation Using Timing Technicalities
Mobile carriers exploit minute-level timestamp ambiguity during number port-outs to charge a full month's bill after service is confirmed cancelled. Customers with ported numbers and no account access are given no credit despite paying for days they cannot use. No independent port timing verification tool exists for consumers.
Telecom Carriers Require In-Store Visits to Cancel Service, Then Charge After Cancellation
T-Mobile refuses remote account cancellations and requires customers to visit a physical store, adding friction that results in additional billing cycles being charged. Even in-store, managers give contradictory instructions about credits while reps on the phone are actively processing them. This deliberate friction in the cancellation flow is a structural customer retention tactic that affects millions of subscribers annually.
