Now I am not able to pay back my Kuwait bank loans and credit card payment as I am Jobless. Currently I got call from Loan recovery agent phone call from india and said me to close the loan asap else they will take legal action at india.Even they start visiting my house and disturbing my families as well. Please let me know following. Can Banks at Kuwait can take legal action at india based on default at Kuwait loan ? Can they register a criminal case to Interpol ? Do this count as financial crime ? How to handle this situation as currently I am not in situation to pay single penny . How to handle this Indian Loan recovery agents who acts for Kuwait banks ? Do it's really legal ?
