We welcome information about practices in the marketplace, but we can’t respond in detail to individual complaints. We won’t normally enter into correspondence about our decisions on whether to give detailed consideration to the complaints we receive.
Contact us if you want to report information about a cartel (such as price-fixing, bid-rigging, output quotas/restrictions or market sharing arrangements).
