Recently, I received a lot of text messages and phone calls, saying that a new friend of mine won't return my phone calls after lending online.

It's not your friend who left your phone number, but the loan software itself will read the phone records and address books and harass the phone numbers contacted by the owners in the near future one by one. There is only one simple way to meet this kind of call, which is to intercept incoming calls and text messages from strange numbers. In addition, there is a simple way to set the call to be forwarded to a stopped number. You can call other people and remind them to turn off their cell phones or stop talking. I did it when I was harassed. It was an accident that someone charged me.
