The problem is not all countries have a hotline or institutions to help with someone's gambling addiction. Even if there are, gamblers are afraid to go there because his neighbor and relatives will discriminate him if they found out that he goes to some group because of his extreme addiction. If someone got to the extent like what the girl did in the OP, his family could bring him to a psychiatrist since they specialize in helping people with mental health problems which I can think gambling addiction also belongs.
