Harrasing

My friend got enggaged with this girl and the enggagement got placed in between parents from both side but on a condition that my friends family will send girl to study visa. When the visa came and they asked for marriage they refused and started making excuses that first they will let goes abriad after then they will call her back nad then they will marry the girl with my friend but in truth they doestn want to make any arrangements for the marriage when they refuse to give the passport of the girl and asked first they have to marry thier with their son and then they will allow the girl to go for abroad and in rwturn the girl parents said they will give ur money back and they dont want this realtionship to go any further and told my friends parent that thier son is mad they dont like him any more whereas on the otherside boy loved her so much and got emotionally attached with the girl and girl comes in her parents talk and refuse to marry my friend now what kind of action could be taken as they have returned all the money
