It's been happening to me too ,for the past month now,just tell them there number will be tracked and that they will go to jail.I just put metro block it back on my cell,i got fed up,that [***] keeps interfering with other calls.
LOL Really they think someone will just give up that info with a threat of a warrant. They should have at least made it more believable. They aren't the only people doing this. I received these calls all the time and I just got my phone.
I've got perfect credit and they are calling me. If you have a iPhone, go to Recent Calls, touch the (i) for information, scroll down to Block this caller, that call number is now on your do not call list. The only way they can call you again is if they call on another number. Then just block that one. Even it happens a thousand times, that is nothing to you. If someone has a real beef with you, they will send a letter, and not play games.
