Short answer: A wrong charge is usually fixed in one phone call, once you reach a person. OsmO makes that call for you from your AI app: you give it the account, the charge and what you want done, and it waits on the billing line, explains the problem and reports back with the outcome and any reference number.
Name the exact charge: the amount, the date and why it is wrong.
Say what fixes it for you: a refund, a credit or a corrected bill.
Leave card numbers, PINs and passwords out of the request; a dispute does not need them.
Ask for a reference number so you can follow up.

The full guide
Good bills to dispute by phone
- A phone or internet bill that went up without warning.
- A fee you were told would be waived.
- A double charge, or a charge after you cancelled.
- A medical bill that does not match what your insurer says you owe.
Give it these four things
- Tell your AI which company to call; it looks up the billing or customer care number.
- Give the account name and number as printed on the bill.
- State the charge, the amount and why it is wrong, in one or two sentences.
- Say what you will accept, and ask for a reference number.
If the charge stands
Plan for a no before the call. Add a line to your request such as "if they refuse, ask for the reason and how to make a written complaint", and OsmO reports what it was told. That gives you what you need for the next step, whether that is a letter, a regulator complaint or a chargeback through your card issuer.
Questions people ask
Is it safe to give OsmO my account number?
OsmO reads it to the agent so they can find your bill; like the rest of your request, it appears in the call's transcript. Never put a card number, PIN or password in a request; a dispute does not need them.
Does it cost more if I am kept on hold for a long time?
No. An answered call uses 3 credits whatever its length, so a long hold costs the same as a short call.
Which countries does it work in?
You can sign in with a mobile number from the United States, Canada, the United Kingdom or Australia (India too). Calls are placed from the OsmO number for your country.
