If, for whatever reason, you want to make a complaint against Rainbow Spins Casino, you can do so by getting in touch with their customer support team, which can be contacted from 09.30 until 18:00. They have a live chat or email option available, and we recommend that you use the former as this is the quickest way to get an issue resolved. If you decide to go for the email option, then you might need to wait up to 48 hours.
