A. What should I do if I suspect a company is contravening, or is likely to contravene a competition rule?
You may contact the Commission to express your concerns and make a complaint. The Commission will consider any complaint that is related to anti-competitive behavior. The Commission also has the discretion to decide which complaints need to be investigated further.
