Bajaj Finance — Debit CMP mandate debit 117/-

I bought an air conditioner 3 years before on EMI from Bajaj fin serv. Now I don't understand why am amount of 117/-was debited from my account showing in the statement Debit CMP mandate Debit Bajaj finance Ltd. Without informing the CUSTOMER why these deductions are done and I am feeling it is not safe even to take LOAN from Bajaj finance also. Agents will say some ### and get the CUSTOMER signed on different documents without informing anything about these type of issues. It is not at all fair to do like these lootings from CUSTOMER. I want to get this mandate cancelled and there should be no more deductions in the name of this. Do the needful
