State Bank Of India — Poor response from SBI Staff to the Customers.

I have a joint Saving/Salary/PMSP Account No.[protected] in SBI KAMAP CODE NO. 15958 . I intend to register my Mobile No.[protected] for SMS alert and in this effect I have submitted a approval form to the staff concerned but the SBI staff concerned refused to register my Mobile Number and asked to submit signature of both Joint Account Holder on the form. As per rules (either or survivor) any one of the Joint Account holder can operate the Account. Kindly look into the matter and direct to the concerned Branch/staff of SBI KAMPA CODE-15958 for this type of non response activity to the customers.
