I am a customer of sbi since last three years. The service of sbi is not all satisfactory. Whenever you want to do a transaction you have to go to the branch where your account exists rather you will charge minimum 50 rupees. Sbi has introduced Greene channel for first transaction but now you have to stand in a Que for making a transaction in the green channel.
The staffs of sbi are not so familiar with a customer like another bank. If you are making good transactions in private banks or small psu banks they will sanction many types of loan to you according to your requirement but at sbi it is not possible for all. Sbi has the largest ATM network nut most of the ATMs are out of order or shortage of 100 rupees note.
