You are able to speak your language with the casino
Many casinos try to translate their site into as many languages as possible. If a casino focuses on a specific country, it often provides customer support directly in the language of that country. If you are not able to speak English, a support like this can be a big plus for you.
A translated website and terms & conditions will make it easier to understand the rules of a casino. To answer potential questions or solve small disputes, you won't have to ask your English speaking friend for help.
Customer support fast and helpful
While visiting an online casino, you often need to verify ambiguities about bonuses, terms & conditions, or the operation of the site.
In the case of customer support, the following applies: the faster, the better. Ideally, customer support will include a 24/7 live chat, with a helpful and friendly person on the other side. The exact opposite is an email address, where you can send your questions and complaints, and then wait three days for an answer; or a phone number you are not able to get through.
