Bajaj Finance Limited - Fraud Transaction

Dear Sir,
Due to covid I'm already facing lot of problems. This bajaj company is creating more problems for me and my family.
On the *nd week of March **** , My family have given the cash to bajaj employees, Executive took the money from my family but it was not updated in their system, Then after a month I got a call from bajaj executive that I haven't paid my last April month of EMI , So to rectify my mistake, I had to pay again on * may **** through net banking. Even that amount has not been updated.
Note :- My last emi of loan no ***SFPFE****** was supposed to end on April ****. I have all the details of my payment till date.
The payment what I did on * may even that is not updated , I have all the required details of my payment except the cash, they took advantage of family innocence.
They have even applied moratorium loan this account. Even though you have received my payment
Why should I apply for moratorium when all my emi are paid . They Purposely tried to withdraw money from my account after April month too. Who is going to pay nach mandate fee. I lost almost Rs **** , The amount was of nach mandate, I do understand if insufficient funds I have to pay the charges but my case is different my emi are cleared ,They Purposely try to withdraw money from my account , I have mailed almost more then ** times , but they ignore my problem.

Please help me out.

Amit Singh
