State Bank Of India [SBI] — against atm machine and pin providing system by

Address: 712502

Dear sir
Myself... I went to bank for replacement of new atm and after received i went to atm machine then after following the instruction to get otp. I got otp but when i am going to change the pin through banking it shows unsuccessful
Only not me here many uncountable guys are suffering for this when i talk to branch staff he said it's having problem to pin change when u r using reliance so plz change the network and use any other.
And if submit a request to change the phone number it will take more than 6 month.

I need to say that plz do something for this bcz the previous system was lengthy but not harassment like this now the days the system is advanced but it's having failure for customer. Why this is happening while atm machine is providing money and showing balance except replacement /new case of atm card and pin.. Bansberia
