State Bank Of India [SBI] — suspicious transfer of balance. recipient of amount not shown in sms

Address:

Sbi freeganj branch, ujjain, m.p., Ujjain, Madhya Pradesh

I received two messages saying that 5 thousand ruppes had been deducted from my account. But in fact about 15 thousand rupees have been deducted according to the chamge in available balance overall.
There is no name of recipient or to whom the mony is tranferrred.
I got these smses after receiving calls from different people in my contact list.

I have no credit or debit card, dont use net banking. Only monthly tranfer to an investment firm, which also recives just one thousand.

Earlier i had received an sms about transfer to the same inveatment firm. Later when members of my family called, i got smses showing this deduction. I said 5 but reduced a greater amount. Please look into my account and
Block and refundd the unauthorised transfer.
