Use your bank’s channel
Use the official app, the number in your banking documents or your branch. BIAT describes blocking through MyBIAT; other banks may use different steps.
Keep a record
Record the time, reference and blocking channel. Ask whether permanent cancellation and a replacement are needed, including fees and timing. Never share your PIN.
Check transactions
Review recent activity through the official service. Report unfamiliar transactions and ask about the dispute procedure. A refund is not automatic.
Useful questions
What should I prepare before contacting the service?
Prepare the relevant reference, dates, a short explanation and useful evidence. Ask for the current document requirements and keep the request number. Do not share secret codes.
Sources and verification
