Hi, I am a citibank debit card holder. On 31st Oct 2011 i used my citibank debit card in ING Vysya bank ATM (Bannerghatta Road branch) near Dominos Pizza. The amount which i entered during transaction was 5000. After around 2/3 minutes thee machine made lot of sound and then it dispersed only 2500 rupees. Currency notes of 500 * 4 and 100 * 5. I am having the transaction slip with me. Immediately i showed the same to the security guard who was available there. He told me to complain the matter to ING Vysya Bank. When i called ING Vysya bank they told me to call to Citibank as thee card was from Citibank. I called Citibank customer care and registered complaint with them with reference number 1110001984. Immediately a credit was made in my account for 2500 rupees and they told me that it will take around 7 days for investigation on this discrepancy. After around a week they called me back and said that after investigation it is found that the transaction for 5000 rupees was valid and the 2500 rupees will be deducted from my account. Citibank deducted 2500 rupees from my account on 15th Nov. I want to know how they investigated on this. I have the original transaction slip, i had even notified the security guard available at that time. If they have CCTV cameras, they can check through that as well. I am in a loss of 2500 rupees because of all this and i want to take this ahead. Please Help me on this.
