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.
When you call they number back the recording states " you have reached the Internal Revenue Services" and to leave your name and number and some one will call you back" Really - 1st if the IRS wants to contact you they will mail you a letter - they do not have time to call you- they will wait for you to call and if you do not and you owe them money they will just take it from you pay check or checking account,,, I wish this number would stop call my number - its stressfull
OUT OF THE USA. From Asia. They are here to spam you. Easy to pay for any "877" number in DC is the main switch and it bounces around to any carrier that is selling your cellphone numbers. Cricket is the worest. Check your carrier's terms and conditions, don't call customer service, they'll lie to you. I know I've done it when working for Verizon....
