ATM non-functioning

I used to draw money from the ICICI bank ATM in our office premise using the Citibank Card. However, for the past 4 weeks all the request had been declined. Even with persistent reporting/queries the problem was not solved. Eventually, this is not the only case. Today an article in 'The Hindu' talks about the same issue with other banks. Would this be a collusion among banks which has more ATMs, after the government order to allow withdrawing money from any ATM ?.
