State Bank Of India [SBI] — state bank of mysore, wilson garden branch, bangalore?`

I have spent lots of time looking for information about state bank of mysore online, only to find that it no longer exist and merged with state bank of india. Neither sbm nor sbi notified me or updated this change. As a sbm customer, it is amazing to notice how they go by doing major changes without the slightest effort to inform and educate their customers about this type of change.

Besides, there is no proper contact information such as email or phone, only third party websites provide information like that and often times are erroneous and incorrect information!!.

Is there anyone out there who knows the correct contact email, phone, fax and address of sbm aka sbi, post merger contacts??. Whom and where the former sbm account holders can go to figure out what happened to their accounts?..
Thank you
