As an absolute layman, I concluded a contract for the repair of declining paneling, which was very overpriced (eg 1m2 penetration cost me 450 CZK, while the actual cost was in the tens of crowns. However, the contract is for a fixed amount I have no advice on how to make this dishonesty uncomfortable (in accordance with the law)? Publish his company - but where and how? Are there any sites that publish the names of dishonest entrepreneurs?
