Why this complaint escalated — and the earliest point it could have been stopped

Refund window

Meridian Mobile internal policy · section 4.1 · fictional, written by the team
Billing disputes other than unauthorised add-ons are refundable for two billing periods from the date the disputed charge appeared.

Outside that window a refund requires a team leader. The two-period limit does not apply where the delay was caused by Meridian Mobile — for example where the customer raised the dispute inside the window and it was not actioned. In that case the original contact date governs.

Agents must not quote the two-period limit to a customer who has already raised the matter once. Doing so is a contradictory answer under policy 6.1.
