State Bank Of India [SBI] — unexpected deduction of money from my account

Address:

Darjeeling, West Bengal

Respected Sir,
In 16/2/2018 a sms comes in my mobile informing" your account xxxxxx has a debit by transfer of rs 147.50..download www.yonosbi.com" ... Without my knowledge and prior permission why this is happening?
As i am merely a jobless youth this is so unethical to deduct my hard earned money in this way.
Kindly resolve this issue and refund my money
