Warranty / Return / Subscription Killer

Your inbox is full of refunds. We claim them.

$19 + 25%Avg find $500$50B unclaimed warranties$300/yr zombie subs

The Finder reads two years of Amazon, Best Buy and Home Depot receipts in your Gmail and flags what’s still under warranty, what you can still return, and every subscription you’ve paid for twice or more. The Closer writes the claim, the return request and the cancel email, and can call the company for you.

One-time $19 payment. Nothing renews, so there's no subscription to cancel. 25% only of money we recover.

Read-only Gmail access, only for the scan. We don’t keep your emails, and you can disconnect any time.

Agent 2 · The Closer

What we send

Warranty claim email

Cites the Magnuson-Moss Warranty Act: free remedy under a full warranty, no voiding over other-brand parts, implied warranties kept.

RMA request

A return merchandise authorization request with your order number, the reason, a prepaid label and no restocking fee for defects.

Cancel email + call script

Cites ROSCA's simple-cancellation rule and your state's auto-renewal law, asks for a refund of the last charge and a confirmation number.

We make the call

An AI voice agent (Bland AI) calls the company, says it's an AI calling for you, waits on hold and gets the confirmation number.

The FTC’s Click-to-Cancel rule was struck down in July 2025, so cancel letters rely on ROSCA (15 U.S.C. 8403) and state auto-renewal laws instead.
