[Resolved]  SBI Personal Loan — Holding my salary

I am holding an account with SBI, Mahadevpura branch. I have avail personal loan from bank of Rs. 300,000 (Rs. 3 lakhs only). I am paying my installments regularly.
I am changing my current job for better prospects. Chief bank manager has hold my this months entire salary without any written concent. When asked verbaly he quoted that he can not trust me for paying further installments as he offered me loan based on my current companies credentials.
I have sent mail to SBI helpline and General Manager consumer service. The complaint no. is 25943631. Is it allowed to hold my salary on hypothetical reasons, when I am not a defaulter and what should be the next step of action.
