Threats and harassment after requesting a loan on an app

Well, I took out a loan on an app, everything was fine until a week passed since I took the loan. Then I started receiving hundreds of calls, the phone vibrated every 5 minutes and it was really annoying. They called me from Ecuador, China, India, the United States, etc. Then I got a WhatsApp message from a Colombian number telling me they were going to come and kill me and sell my organs, with threats. Then they sent me photos of my own ID as a threat, and later one saying they were going to burn me alive along with my whole family, that they were going to take me to Colombia and that I would suffer for trying to steal their money. Almost a month has passed and no one has come to my house, they stopped bothering me, so I can conclude that they just wanted to scare me and force me to pay more than I borrowed. Be careful with this.
