This thing was experienced by me, during the demonitization I am unable to find any working ATM's near my home , even though I live in city. I faced many problems , But state bank provided me ATM's with full cash.
The cash depositor machine too played a best role in exchanging the money.
When compared to other banks I personally felt that State bank provided me a very good service to its customer.
Even though the quequ was very long but it provided enought, suffiecient cash for everyone.
