If your bank denied a debit-card fraud claim, save the records you already have.
Start with the denial letter or email. Save your bank statements showing the disputed transactions, fraud alerts or text messages, emails from the bank, and anything showing when the bank canceled your old card and issued the replacement.
If you have notes about telephone calls with the bank, keep those too. If you sent screenshots, a police report, a written statement, or other documents, save copies of what you sent.
Then put together a basic timeline:
When did you first notice the fraud? When did you report it? When did the bank cancel the card? Did additional transactions happen afterward? When did the replacement card arrive? When was the claim denied?
You do not need to turn yourself into a private investigator.
The point is simply to preserve the story while you still have the records.
Maybe you have already built a beautiful file containing everything that happened. Great.
Maybe you have a pile of bank letters and absolutely no idea what matters. That is okay too.
You do not have to figure the whole thing out before asking for help.
