Please friends listen too me. If you want good bank service choose any bank except this Indian Overseas Bank. In this bank dont have any proper faclities like mobile sms alert, otp etc. As proof I tell my story attached to this idiot bank I requested the letter to them as to change my mobile number. But that not done. I wasted 8months to this bank to change the number. They simply said server problem. But they dont take any action. Please friends as I sufered to this problem. Like this dont interfere to this bank.then you only made with trouble.i only know about my feelings. Iam not transact even single money to any one to my urjent purpose. Please make think over
