Alternative Consumer Dispute Resolution (known as RAL) covers mediation, conciliation and arbitration.

Independent entities, with specialized personnel, impartially help the consumer and the company/professional to reach an amicable solution through mediation or conciliation.
If this agreement is not progressive, you can still appeal to the arbitration court, through a simple and quick process and in most cases free of charge.
