If I have a complaint about a bank, where do I go?

No. Banking institutions have their own ombudsmen. You must send your complaint to them. See the website of the bank in question for the contact information about the ombudsman.

If your situation has not been resolved after this step, contact the Ombudsman for Banking Services and Investments.

If your complaint concerns a public fund manager, contact the Autorité des marchés financiers instead.
