If you have any complaint, first read the terms and conditions to be sure it’s valid. Submit your complaint via one of the customer service portals. (For severe complaints, e-mail is best as you then have a record of responses). Suppose you are unhappy with Casino Planet’s reaction. In that case, you can escalate the complaint to an official complaints resolution service for arbitration or mediation. These are known as Alternate Dispute Resolution (ADR) in the UK or Online Dispute Resolution (ODR) for the EU. In arbitration by an ADR or ODR, the decision is legally binding on both parties. Mediation decisions are not legally binding.
