Bajaj Finance — Bajaj Finance-117 cmp mandate debit from account

117 has been deducted from account towards Bajaj Finance — cmp mandate debit from account with no intimation, I have finished emi's like 8yrs before and havent used the their service since then. I know they have our details that doesnt mean they can misuse them and deducted as per their wish . Bajaj Finance seems to be fraud as it loots ppl by using their details. I want my money refunded and wouldn't entertain further if any such transactions are performed without any intimation .
