In my opinion, the casino is very rare who has a discussion group and dispute in the telegram because it will only make a long debate and later make a problem more difficult.
Therefore Casino prefers to accept and provide their services to every complaint or problem that has occurred to customers in a chat with a support team because it is more private and there is no interference from several other customers.
Everything that has been done and given by the casino certainly has a good goal because they do a business that does not want if there is a fatal and prolonged problem of the casino business they have run.
