Every time I ask for that money he keeps cheating that I will give it to the Hindu tomorrow everyone in his house knows this thing but everyone has blocked my mobile me. If you ask me to return that house, he did not give us that house. My son will scold me. My son will destroy you. He threatens not to go to that house.He has cheated us by giving us a lot of checks and he will tell us to withdraw money from the bank on this date but on that date there will be no money in that bank and that return will come.I do not know what to do.
