How to prove what a company told you on the phone
An agent says the fee is waived, the date is extended, or the charge will be reversed. Weeks later, a different agent says no such thing was promised. Verbal promises vanish unless you capture them. Here is how to hold a company to what it actually told you.
Record the call where your state allows it
A recording is the cleanest proof of a promise. Whether you can record depends on your state. Some states let one party to the call record it, others require everyone to consent. See call recording laws by state and how to record a customer service call.
Capture the details in the moment
On every call, write down the date and time, the agent name, a reference or call number, and the exact promise in their words. Ask the agent to add a note to your account and to read back the reference number. These details turn a vague memory into a record.
Get it in writing
Ask for written confirmation by email or message, and follow up your own summary in writing. If a debt collector is involved, putting your dispute in writing matters: you generally have 30 days after first contact to ask the collector to verify the debtsource. A written record is hard to walk back.
Keep your proof in one place
Save the recording, the written confirmations, and your notes together so you can produce them on the next call. CaseHero is built for exactly this: it keeps your own recording of the call, transcribes it, and pulls out what you were promised, so you can quote it back word for word.
Frequently asked questions
Is a recording proof a company will accept?
A recording is strong evidence of what was said. Combine it with written confirmation and your notes for the strongest record. This is general information, not legal advice.
Can I record without telling the company?
It depends on your state. In one-party states a participant can record, in all-party states everyone must consent. See call recording laws by state.
What if I did not record the call?
Write down everything you remember right away, ask for written confirmation, and dispute in writing. If a collector is involved, you can request validation of the debt within 30 dayssource.
