Cash Bus — Complaint about harassment for loan repayment which I didn't receive

Dear Sir,
As i applied for a loan on 19/8/22 later on 21/8/22 the app shows the loan has been sanctioned and the repayment date is on 26/8/22 The truth is i applied for loan but i didn't get any amount credited to my account. I contacted through they website fortunately some one did respond to my mail, then i shared my Bank statement to them, by looking at the statement they believed me, now they are resolving my issue, they said that my payment has failed due to some wrong information, they are trying to balance the account but the employee in WhatsApp ([protected]) is harassing me telling me that he will ban my Aadhaar card, PAN card etc and he also said he will send a message to all my contacts that I'm a fraud.
I even shared the screenshots of the mail to him (in WhatsApp) but he is not at all bothered about that, he keeps on torturing me, blackmailing me asking me to repay the amount which i haven't received. Even after lot of attempts of explaining the situation he keeps on torturing me.
So i decided to complaint with a hope you resolve it.
I hope you understand and do the needful.
