Bank account blocked

Hi,

In december 2024 I sold 0.01 btc to EUR via SEPA with bisq.
I’ve traded lots of trades this way with bisq since 2020 and I love it.
However, this is the first time things went wrong.

Since a week my bank account has been frozen by the bank. After lots of email contact with my bank I learned that the Bisq Buyer filed an report to my bank and accousing me of fraud. That is why my accounts are all blocked now.

The trade in bisq however was succesfull. We both paid 0.005 security deposit and in the end the 0.015 (amount + security deposit) was send to the buyer and the 0.005 security deposit came back to me.
Now I’m thinking that after a succesfull transaction this person is trying to get back the euro’s from my bank by saying that I committed fraud, which is obviously not true!

I still have the name and bank account number of the buyer
Is there someone to who can I give this information so that this person or account number can be blocked from bisq?
Or is this just a case of bad luck?
What more can I do so this will not happen again?
Are there more people having this similar problem?

Thx

This is not frequent. It will be really strange that your peer is successful with the chargeback if the transaction was made more than a month ago.

Go to bisq.chat and contact a mediator so you can provide sensitive data and this buyer gets a ban: Finding your mediator - Bisq Wiki
