They told me they would refund me.
Suppose you’ve already made the call. You explained the charge, waited while someone checked your account, and got an answer: the money would be returned. You saved the recording. As far as you were concerned, that was dealt with.
Then the next statement arrives.
On the second call, the person helping you can’t find a refund approval. You explain the charge again. Then you explain the first call. Somewhere in the process, getting your money back has become a discussion about another discussion.
At least you have the recording. You can find the relevant part, check for any conditions you missed, and let the next person hear what you heard. Perhaps that clears things up.
Until you share it, though, the recording has a history familiar only to you. It’s been sitting on your phone since the first call. To someone receiving it today, it’s a new attachment. They can listen to the words, but listening won’t establish when you had that particular version.
Audio can be spliced, screenshots rewritten, and photos altered. AI adds more ways to make changes convincing. If a file is questioned, “that’s how I saved it” is still something another person has to take your word for.
You could be completely honest and wish you had a better answer.
An independent timestamp gives you something checkable: evidence that this exact version already existed by a particular time. If that time falls before the disagreement, it helps answer the suggestion that you changed the file afterward.
They Told Me by ProofStamp lets you create that checkpoint while you’re saving a conversation you may need later. It works with recordings and screenshots you already have. It doesn’t record calls. You can include related files, such as the bill and a written follow-up, in the same package.
On your device, the app calculates hashes, values derived from the files’ exact contents that let software check for a match. An independent service timestamps a record of those values without receiving the original files.
You download one .proofstamp.zip with your originals and their proof. Keep it intact, somewhere you’ll look when you need the recording. There’s no account or cloud copy to recover it from.
Now return to that second call. You have the recording, and you also have the proof you saved before the refund became an argument. Choose Check ProofStamp in the app and open the ZIP. It checks the enclosed files and timestamp signature, then shows the signed time. Someone you share the package with can do the same.
A later edited copy would fail to match the earlier proof. So would a harmless conversion to another audio format, which is why keeping the package with its originals matters. The check establishes a match, without trying to guess whether AI or any other editing tool was involved.
Someone could fabricate a recording before timestamping it. That file could pass verification. A timestamp cannot identify the speaker or establish whether the contents are true or complete. And stamping an old file today gives you today’s checkpoint, regardless of an earlier date in its filename or metadata.
The easiest moment to do this is at the end of the first call, while the recording is right there and you still think the problem is sorted. Save the ProofStamp along with it.
Ideally, the refund arrives and you never open that ZIP again.
