State Bank Of India [SBI] — state bank of india phone banking is really frustrating

Address:

State Bank of India

I transferred money to my father's sbi account in january successfully via phone banking. But now in february and march i can't transfer amount because of absence the option generate otp during phone banking. Against this i talked to more than five sbi customer care executives but all are helpless they really don't know anything about state bank of india that's why i am really frustrating with state bank of india and also with sbi's customer care services & i really know this problem is existing with with all state bank of india's customers. I really want to know when this problem would be resolved? Sbi is really frustrating to each and every customer.
