[Resolved]  State Bank Of India [SBI] — balance enquiry service not working since long time via sms or missed call

Address:

Mumbai City, Maharashtra

Balance enquiry service not working since long time via SMS or missed call
I used to call [protected] to get my SBI account balance
But for a long time now this number is always not working
Including [protected] for mini statement

SMS Banking and missed call service have been not working for a long time
I'm not sure whom to contact because customer service has no clear information every time I call them
I've tried to call SBI customer but they haven't fixed this issue
Can this be escalated to the right channel
