Axis Bank — atm fraud

Address:

Chennai, Tamil Nadu

once i went to ATM to take out some money and found that there was some issue with taking out the money so i went to a different ATM and the same issue happened however i found that other people were able to take out the money so i thought that its my banks server which might be down so i came home firstly the message that comes after you debit the amount comes after one day or half an hour.To my utter surprise i came back home and found two message that my account was debited 2 times with 2000 rupees where i could not get any money out of it so i had to Waite for Monday as it was Saturday where the bank customer care do not work till Monday.On Monday i gave them a call and found out that they had issue and they promised me that they will pay me the money within 7 working days so i kept calm and Waited.at that time i had 4000 rupees left on my account and i took out 1000 rupees from it so i had 3000 rupees left after few days i saw 5000 rupees on my account which i could see only after checking my account as there was no message that the amount was credited i thought that only one transaction was credited and rest will be credited later and out of curiosity i gave a call to the axis ban customer care and they said that they have credited both the amount to my account usually account to my math if 4000 gets added to my account it should become 7000 and not 5000.its a clear fraud as its a hard earned money which should not go to vain please let me know what to do
