Undue charges appear when least expected: an extra amount on the bill, a service you do not recognize, or a fee that was never agreed upon. In many cases, the error is simple. In others, it may be a sign of an abusive practice or a scam.
Organization makes a difference. Keeping documents, checking details, and knowing how to dispute charges avoids rework and gives consumers more leverage. Below are three common pitfalls in Brazil — and how to avoid them.
Pitfall 1: charges without itemization
A generic charge is fertile ground for error and abuse. Vague terms such as “administrative services,” “operational fee,” or “technical adjustment” make verification difficult and discourage questions.
What to watch for in practice:
- Bills or payment slips without itemized items - Services described differently from the contract or quote - Rounded amounts with no explanation
How to avoid it:
- Always demand itemization of services and amounts - Compare the charge with what was contracted, line by line - Do not accept a “phone explanation” without written records
Pitfall 2: recurring charges after cancellation
Plans, subscriptions, and ongoing services lead this type of problem. The consumer requests cancellation, receives a protocol number, but the charge keeps appearing in subsequent months.
Warning signs:
- Automatic debit maintained after the cancellation request - A new bill issued even without using the service - Difficulty locating proof of cancellation
Good practices to protect yourself:
- Keep protocol numbers, emails, and screenshots of the confirmation - Write down the date, time, and channel used for cancellation - Check the following bills with extra attention
Pitfall 3: pressure to pay before disputing
Scammers and ill-intentioned companies use urgency as a strategy. Phrases like “if you don’t pay today, your name will be reported as delinquent” or “it’s easier to pay and sort it out later” put the consumer at a disadvantage.
When to be suspicious:
- Immediate threats without formal notification - Very short payment deadlines - Refusal to open a dispute ticket
How to act calmly:
- Request the charge in writing with a clear deadline - Register the dispute before making any payment - Avoid negotiating solely through messaging apps
Organization: the step-by-step that helps with disputes
Having a method reduces stress and speeds up resolution. A simple checklist usually works:
- Gather contracts, quotes, bills, and receipts - Highlight the amount or item you consider undue - File the complaint through a single official channel - Record protocol numbers and stated deadlines
This organization also helps if the case needs to be taken to consumer protection agencies.
Beware of scams disguised as charges
Not every undue charge comes from a company you know. There are cases of fake payment slips, emails impersonating real companies, and contacts requesting payment via Pix for “regularization.”
Essential precautions:
- Check the beneficiary’s details before paying - Be wary of unexpected charges by email or message - Do not click on attachments or links from unknown senders
Information is the consumer’s best defense
Mistakes happen, but undue charges should not be treated as normal. Questioning, requesting clarification, and keeping records are simple actions that empower consumers and reduce room for abuse and scams.
