Myself, my wife and minor son were at KLIA last week for returning back to India after a month's stay at Kuala Lumpur for medical reasons. After checking our passports, my index fingers of both hands were finger printed after the passports were taken inside by the immigration officer inside some cabin for about 15 minutes. After the same was done, we received our passports and were orally told in a discourteous and rude manner that we should not enter Malaysia for next 5 years, but no endorsements were made in the passports and visas. We have no clue as to what is happening and why such an oral order and inappropriate way of treating us. We showed all the documents and were having all proofs to show our valid stay. Please advise us what is to be done. We were not given any opportunity to speak anything and were just praying to return to our country safely.
