State Bank Of India [SBI] — transaction without authentication and prior notice

Address:

Nalgonda, Andhra Pradesh, 508001

On 06/03.2018, I have received an sms from SBI official portal that a sum of Rs. 295/- was debited from my Savings account no [protected] transferred to INVESTMENT INTERMEDI. This is third time, I have been complaining.

However, till date I have not made any investment to any of the above named company, neither taken any policy or so, ...it was a complete out of blue pop up to me and really don't have any clue on what ground this amount has been debited and how to recover it back.
