Large Taka — Loan harrashment

On 26th December, I got a loan of Rs 2400 from Large Taka App, in return, they asked me to pay 4000 Rs. Threatened to send my nude photos to all of my contact lists if not paid.

I pay them 2000 Rs on 9th January 2023 the remaining 2000 which although I am not supposed to pay I commited them to pay after 20 days.

Now the problem is that the representative who was handling this case claiming does not know anything about it, meanwhile their app meter is increasing daily for interest.

Please help me to get rid of them
