State Bank Of India [SBI] — credited hold in my account without any reason

Address: Mathura, Uttar Pradesh, 281006

My name is dinesh kumar and i have account in sbi mathura cantt (Branch code-05716). I received sms from state bank of india on 05 sep 2017 that hold credited in my account for 199 rs. And 209 rs. Without any reason and today i received a same sms that hold credited in my account for 100000 rs.
I worried so i called sbi toll free number [protected] but they said you have to talk in your branch for this.
Customer care not telling me that what is the reason for hold in my account. I don't have any due from bank and not any loans, so why are they doing this.
Worst service by sbi service branch (Sbin0005716) mathura cantt.
Please help me
