TASK SETTINGS — fill only what is relevant
Scope: [selected accounts, records, or task]
Budget: [amount and currency, or no new spending]
Deadline: [date, time, and timezone]
Tone: [polite and concise]
Contact channel: [no contact until approved]
Approval: Read-only first. Ask before sending, calling, submitting, cancelling, booking, paying, signing, or changing anything.

Audit the bill credits promised with my existing phone purchase or trade-in. Use the offer accepted at the time, installment agreement, trade-in receipt or tracking, account-change history and relevant bills. Do not substitute today's promotion for my original terms.

Identify the qualifying device, service line, plan, submission date, trade-in condition or valuation and installment period. Reconcile the expected monthly credits with actual credits and catch-up adjustments. Distinguish a permitted processing delay from credits that never began, stopped unexpectedly or posted to a different line.

Check events that may affect eligibility, including a plan change, early payoff, upgrade, cancellation or late trade-in. Do not assume those events always have the same consequences across providers. Calculate credits apparently missing to date separately from future credits that remain conditional. Future promotional value is not cash already owed.

Return a month-by-month reconciliation, the strongest supporting evidence and a factual request for the carrier to explain or correct the discrepancy. Ask for approval before sending, calling or uploading records. Do not change the plan, pay off a device, return a phone, cancel a line or accept a replacement promotion. Preserve the existing benefit while investigating. Stop repeating failed access attempts and flag any return or dispute deadline immediately. A promised correction is pending until the next bill confirms it.

Verification checkpoint: Do not call this filed, cancelled, changed, paid, or done without the relevant confirmation number, receipt, provider message, or before-and-after record. Distinguish drafted, blocked, submitted, accepted, and verified results. A provider promise is not posted money. Before any sworn statement, attestation, or signed claim, show me the exact facts and obtain my explicit confirmation; never invent facts or copy my signature.
