State Bank Of India [SBI] — state bank of india bank account stopped without intimation

Address:

Chennai, Tamil Nadu, 600042

My account is being closed without any prior intimation. Had attempted fund transfer multiple times but this app never told about exact issue rather always said Success.
They have worst customer care service across banks. Call never been picked. Email never been answered. Consumer complaint could never been submitted due to tech issue. Only option they provide is to reach branch I am very sure that sbi is so outdated in technology. In this age of technology they are asking consumer to go their branch and do all manual work. Come on sbi...we don't have all spare time to queue up in branch. At least branches should help rather that simply putting on other branhces.
